Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE Micro - it's an Atmega32u4 chip (same as used as in the Adafruit Flora or Arduino Leonardo) plus our SPI Bluefruit LE Friend in one.
If you've been diggin' our monochome OLEDs but need something bigger, this display will delight you. These displays are 2.3" diagonal, and very readable due to the high contrast of an OLED display. If you've been diggin' our monochome OLEDs but need something bigger, this display will delight you. These displays are 2.7" diagonal, and very readable due to the high contrast of an OLED display. This display is made of 128x32 individual white OLED pixels, each one is turned on or off by the controller chip.
If you've been diggin' our monochome OLEDs but need something bigger, this display will delight you. These displays are large and very readable due to the high contrast of an OLED display. This display is made of 128x64 individual white OLED pixels, each one is turned on or off by the controller chip.
It's summer and you're sweating and your hair's all frizzy and all you really want to know is why the weatherman said this morning that today's relative humidity would max out at a perfectly reasonable 52% when it feels more like 77%. Enter the HDC1008 Temperature + Humidity Sensor - the best way to prove the weatherman wrong!
Wouldn't it be cool if, instead of having to give your dog-sitter a key to your place, you could just text your home to let her in? Now we build it ourselves using the new Lockitron body, Metro Mini (tiny Arduino-compatible) and a FONA 800 cellular module. Normally, a Lockitron has a built-in WiFi system for locking & unlocking via their App. Since they have redesigned their enclosure, we now have the 'guts' of the Lockitron available for hacking. There's just enough space inside for some tasty Adafruit electronics
Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is 2.4" diagonal with a bright (4 white-LED) backlight and it's colorful! 240x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
Would you like to add powerful and easy-to-use Bluetooth Low Energy to your wearable FLORA project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Flora Bluefruit LE! The Flora Bluefruit LE makes it easy to add Bluetooth Low Energy connectivity to your Flora. Sew 4 traces (or solder 4 wires) and BooM! Bluetooth Low Energy!
Is this not the cutest little display for the Raspberry Pi? This HAT features a 2.4" display with 320x240 16-bit color pixels and a resistive touch overlay. The HAT uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top!
Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don't have an onboard 250mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified....UNTIL NOW!
PowerBoost 1000C is the perfect power supply for your portable project! With a built-in load-sharing battery charger circuit, you'll be able to keep your power-hungry project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects.
A TFT panel connected to a Raspberry Pi without the use of an HDMI decoder? What is this sorcery??? It's the DPI Kippah from Adafruit! This HAT-like board snaps onto a Raspberry Pi B+, A+ or Pi 2 Model B and with a little software configuration, allows you to have what normally would go out the HDMI port come up on a nice little flat screen.
Fire four solenoids, spin two DC motors or step one bi-polar or uni-polar stepper with 1.2A per channel (3A peak) using the TB6612. These are perhaps better known as "the drivers in our assembled Adafruit Motorshield or Motor HAT." We really like these dual H-bridges, so if you want to control motors without a shield or HAT these are easy to include on any solderless breadboard or perma-proto.
XBee modems are one of the easiest ways to create a wireless point-to-point or mesh network. They have error correction, are configured with AT commands, come in multiple flavors and can create a wireless serial link out of the box! I wanted to make a wireless Arduino project but all the adapter boards on the market made me unhappy. So I designed what I think is an excellent low-cost adapter board.
The Raspberry Pi is a wonderful little computer, but one thing it isn't very good at is controlling DC Servo Motors - these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on this handy HAT! It adds the capability to control 16 Servos with perfect timing. It can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running.
