A level shifter just for pixels 🔌✨💡

After noodling with some WS2811s and TM1814, we really wish we had a board that would level-shift our NeoPixel signals from 3V to 5V or give us an inverted data line. So, we designed this board. It uses an AP3602

charge pump to give a clean 5V reference voltage from 3~5V. A 74HCT2G34

shifts two signals - we call them DAT and CLK, but it could be anything really - to 5V from 1.8~5V. Finally there's an 74LVC1G04

inverted data output line for TM1814 and other weird chips. Terminal blocks on either side make this a no-solder board. There's also a single disableable 1.5mm NeoPixel on the DAT line for testing the WS281x signal coming through OK. Coming soon.
