       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 (https://www.digikey.com/en/products/detail/diodes-incorporated/AP3602AKTR-G1/5305823) charge pump to give a clean 5V reference voltage from 3~5V. a 74HCT2G34 (https://www.digikey.com/en/products/detail/nexperia-usa-inc/74HCT2G34GW-125/1300830) 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 (https://www.digikey.com/en/products/detail/texas-instruments/SN74LVC1G04DBVR/385716) 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.
