# Leverless Controller ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/144/189/medium800/gaming_lvrls-1917.jpg?1779300361) https://youtu.be/vJaKmj5k3Sw So called "leverless" controllers are popular among fighting game enthusiasts for their speed and accuracy compared to traditional lever-style joysticks. You can build your own with the Adafruit QT Py RP2040 and GP2040-CE firmware. Mini arcade buttons are mounted to a 3D printed case (or BYOB(ox)) to make for a playable, ergonomic design. And by wiring the buttons to the QT Py Terminal Block BFF using quick-connect cables, you can keep the build manageable and nearly solder-free -- the only soldering required is the QT Py header pins. Since the GP2040-CE firmware can be configured from a web browser, this project is essentially code free -- just drag and drop the UF2 and you're ready to play. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/182/medium800/gaming_IMG_1912B_2k.jpg?1779235651) ## Parts ### Adafruit QT Py RP2040 [Adafruit QT Py RP2040](https://www.adafruit.com/product/4900) What a cutie pie!

The diagram above shows the wires connected to the QT Py for clarity, but you'll be using the Terminal Block BFF for the real thing. # Leverless Controller ## Software ## Install Firmware and Customize Settings [GP2040-CE](https://gp2040-ce.info/#/installation) is an open source gamepad firmware that's compatible with RetroPie, Mac/PC/Linux, PlayStation 3/4/5, Nintendo Switch/Switch 2, Xbox 360/One/Series, mini consoles, and others. It runs on a number of microcontrollers which use Raspberry Pi RP2040/RP2305 chips, such as The QT Py, Pico, [KB2040 Kee Boar](https://www.adafruit.com/product/5302), and more. First you'll flash the QT Py RP2040 with the drag-and-drop .uf2 file and then customize settings within a web editor. ## Download Firmware There isn't an official build for the QT Py RP2040 yes, but you can use [this pre-release version](https://github.com/jedgarpark/GP2040-CE/releases) by clicking the **GP2040-CE\_0.7.12\_AdafruitQTPyRP2040.uf2 ** file. This will save a file named  **GP2040-CE\_0.7.12\_AdafruitQTPyRP2040.uf2** to your download location. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/173/medium640/gaming_build.jpg?1779167661) ## Firmware Installation [This page](https://gp2040-ce.info/installation) gives detailed instructions on installation, but the basic steps are: - Plug the QT Py RP2040 into your computer with a known good data and power USB cable - While holding the `BOOTSEL` button down, press and release the `RESET` button this puts the board into  **BOOTSEL** /USB drive mode - A new removable drive named `RPI-RP2` will appear on your computer - Drag-and-drop the **GP2040-CE\_0.7.12\_AdafruitQTPyRP2040.uf2**  (or later) firmware  **.uf2 ** file onto the `RPI-RP2` drive and wait for it to copy the file and reboot itself ![](https://cdn-learn.adafruit.com/assets/assets/000/144/174/medium640/gaming_gp2040logo.png?1779167887) ## Pin Mapping The default pin mapping in GP2040-CE for the QT Py RP2040 is shown here. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/175/medium640/gaming_qtpy-rp2040-pins.jpg?1779167962) ## Button Test This is a great time to test the controller to make sure basic button presses are working. Plug the QT Py RP2040 into your computer with a known good USB-C data and power [cable](https://www.adafruit.com/product/3879). Head to this [gamepad tester](https://hardwaretester.com/gamepad) in your browser to see the button presses. You can now use a jumper wire to short any mapped GPIO pin to ground -- those button presses will register on the controller tester.  ![](https://cdn-learn.adafruit.com/assets/assets/000/144/176/medium640/gaming_tester.jpg?1779168131) # Leverless Controller ## Build the Controller ![](https://cdn-learn.adafruit.com/assets/assets/000/144/230/medium800/gaming_lvrls-1924.jpg?1779302289) ## Solder the QT Py Headers Solder the male header pins on to the QT Py RP2040 as shown here. You can optionally use [short headers](https://www.adafruit.com/product/3002) for a slightly lower profile, but the default pins included with the QT Py work just fine. See the guide [How To Solder Headers](https://learn.adafruit.com/how-to-solder-headers) for how-to and tips. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/192/medium640/gaming_lvrls-2013.jpg?1779300441) ## Mount the Terminal Block BFF to the Case Mount the Terminal Block BFF with the larger battery JST connector facing up as shown. Screw the M2.5 x 10mm screws in from the top into standoffs or nuts on the inside of the case. Use a small slotted screwdriver to open all of the terminal positions by unscrewing them counter clockwise in prep for wiring later. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/193/medium640/gaming_lvrls-2009.jpg?1779300508) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/195/medium640/gaming_lvrls-2011.jpg?1779300557) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/196/medium640/gaming_lvrls-2007.jpg?1779300586) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/197/medium640/gaming_lvrls-2005.jpg?1779300596) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/198/medium640/gaming_lvrls-2004.jpg?1779300691) ## Add QT Py Press the QT Py into the terminal block BFF with the USB port facing up as shown. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/200/medium640/gaming_lvrls-2001.jpg?1779300731) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/201/medium640/gaming_lvrls-1998.jpg?1779300749) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/202/medium800/gaming_lvrls-1995.jpg?1779300764) ## Arcade Buttons Insert an arcade button into to the case from the top and then screw on the retaining nut. Repeat this for the remaining buttons. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/203/medium640/gaming_lvrls-1993.jpg?1779301411) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/204/medium640/gaming_lvrls-1992.jpg?1779301422) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/205/medium640/gaming_lvrls-1988.jpg?1779301448) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/206/medium640/gaming_lvrls-1983.jpg?1779301462) ## Cable Prep Prepare the cables by first cutting off the white plastic JST connectors (be sure to keep the terminal connector ends intact), thereby separating each pair into two individual cables. Then, strip about 4mm of insulation from the bare end of each cable. Twist the wire strands so they don't fray and potentially short against neighboring pins when inserted into the terminal block later. Repeat these steps for all remaining wires for a total of 22 (that's two wires per button). ![](https://cdn-learn.adafruit.com/assets/assets/000/144/207/medium640/gaming_lvrls-1975.jpg?1779301507) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/231/medium800/gaming_leverless_fritz5.jpg?1779302362) ## Connect Button GPIO Following the diagram carefully, wire one terminal of each button to it's associated pin on the QT Py via the Terminal Block BFF. First, press the cable's crimp connector onto one of the button's two switch terminals (these are the two at the top of the switch, not the one's at the bottom with the arrows and +/- signs, those are for the LEDs, which we won't be using). Then, run that wire through the case and to the terminal block pin for that button. Screw the terminal screw down tight. Repeat for remaining 10 buttons. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/208/medium640/gaming_lvrls-1977.jpg?1779301579) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/209/medium640/gaming_lvrls-1976.jpg?1779301595) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/210/medium640/gaming_lvrls-1979.jpg?1779301613) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/211/medium640/gaming_lvrls-1982.jpg?1779301633) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/212/medium640/gaming_lvrls-1981.jpg?1779301641) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/213/medium640/gaming_lvrls-1980.jpg?1779301649) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/216/medium800/gaming_lvrls-1956.jpg?1779301810) ## Ground Run Cut a 20cm length of 22AWG stranded wire ([this spool set](https://www.adafruit.com/product/3111) is handy to have around), then strip about 4mm of insulation from each end. Feed this wire through the case and into the GND position on the QT Py/BFF. Screw it in place. Then, inside the case, connect the other end of this wire to any position on the 3-wire block connector. Chain together all of the block connectors using 6cm lengths of stranded wire with 4mm of insulation stripped from each end. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/217/medium640/gaming_lvrls-1952.jpg?1779301874) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/218/medium640/gaming_lvrls-1948.jpg?1779301908) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/219/medium640/gaming_lvrls-1944.jpg?1779301936) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/220/medium640/gaming_lvrls-1943.jpg?1779302026) ## Cover Lots of Ground Fast Now you can press the remaining 11 crimp connector cables onto the second switch position of each arcade button (again, avoiding the lower two LED legs). For each button's ground wire, connect the free end to any open position on a block connector. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/221/medium640/gaming_lvrls-1954.jpg?1779302032) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/222/medium640/gaming_lvrls-1942.jpg?1779302045) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/223/medium640/gaming_lvrls-1940.jpg?1779302057) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/224/medium640/gaming_lvrls-1935.jpg?1779302068) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/229/medium800/gaming_lvrls-1934.jpg?1779302255) ## Case Closed Press fit the bottom onto the case as shown. ![](https://cdn-learn.adafruit.com/assets/assets/000/144/225/medium640/gaming_lvrls-1933.jpg?1779302195) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/226/medium640/gaming_lvrls-1930.jpg?1779302221) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/227/medium640/gaming_lvrls-1932.jpg?1779302231) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/228/medium640/gaming_lvrls-1929.jpg?1779302242) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/232/medium800/gaming_lvrls-1922.jpg?1779302389) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/233/medium800/gaming_lvrls-1921.jpg?1779302407) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/235/medium800/gaming_lvrls-1920.jpg?1779302438) ![](https://cdn-learn.adafruit.com/assets/assets/000/144/234/medium800/gaming_lvrls-1919.jpg?1779302417) # Leverless Controller ## Configure and Use the Controller ## Web Configurator Press and hold the START (S2) button (the one wired to QT Py RP2040 pin **SCK (GP06)** ) and then press and release the  **RESET**  button.
