Slide Switch JST AdapterUse a 2-pin JST female and male cables to get a slide switch JST adapter. This allows the power to be cut from the battery. The switch is wired in-line with the voltage (red) wire. |
|
Wired Slide SwitchSolder the ground wires from both JST cables together. Solder the two voltage wires to the middle pin and either side pin on the slide switch. Use pieces of heat shrink tubing to insulate the exposed connections. |
|
NeoPixel Jewel JST CableA male 3-pin JST cable is soldered to the DIN, 5V and GND pins on the NeoPixel Jewel. |
|
NeoPixel Jewel JST CableSolder the red wire to the 5V pin, the black wire to GND and the white wire to the DIN pin on the back of the NeoPixel Jewel. |
|
Wired NeoPixel JewelDouble check the solder joints are solid. Note, the cable in the photo is silicone stranded cover ribbon wire. |
|
Cables for GEMMA M0A female 3-pin JST cable and 2-wire ribbon cable is soldered to the GEMMA M0. |
|
Connect 3-pin JST to GEMMASolder the white wire to D2, black wire to GND and red wire to 3V. |
|
Connect 2-wire Cable to GEMMASolder the 2-wire ribbon cable to the GND and VOUT pins on the GEMMA M0. |
|
Wired GEMMA M0The ground pin on the GEMMA M0 shares common ground with the JST cable and 2-wire ribbon cable. |
|
5V MiniBoost HeadersInstall a 4-pin male headers to the 5V MiniBoost. This will make it easier to attach multiple wires to the pins. |
|
Installed HeadersTin the pins on the headers by adding a bit of solder. This will make it easier to attach wires to the pins. |
|
5V DC FanThe fan comes with pre-soldered ground and voltage wires. Silicone cover stranded core wires can be substituted for stronger more flexible wires. |
|
Wiring Gemma and Fan to BoostThe GEMMA M0 and 5V fan are soldered to the pins on the 5V MiniBoost. The 5V MiniBoost provided the fan with proper 5V with 1A current. |
|
Wiring BoostSolder the wires to the following pins:
|
|
Wired GEMMA and 5V FanDouble check the solder joints are solid. |
|
Circuit TestingConnect the NeoPixel Jewel to the GEMMA M0. Connect the slide switch JST adapter to the GEMMA M0 and 2200mAh battery. Ensure the fan blades are not being obstructed before powering on. Use the switch to power on the circuit. Ensure the on/off switch on-board the GEMMA M0 is set to the ON position. |
