5V
NeoPixel Jewel power input. Adafruit product page states to power the board with 5VDC; the NeoPixel guide describes +5V as the positive power input.
Type · powerVoltage · 5V DC
GND
Ground return for the NeoPixel Jewel power and controller reference. The NeoPixel guide states GND must connect to the supply minus terminal and microcontroller GND.
Type · groundVoltage · 0V reference
DIN / DI
Single NeoPixel data input from a microcontroller. The product page states there is a single timing-specific data line and the guide identifies DIN/DI as data input.
Type · signalVoltage · 5V data preferred when powered from 5V; 3.3V data is acceptable when NeoPixels are powered from a 3.7V LiPo per Adafruit guide
DOUT / DO
Data output for chaining to the DIN/DI input of the next NeoPixel Jewel. The product page states LEDs are chainable by connecting output of one Jewel into input of another; the guide says DOUT/DO may be left unconnected at the end of a chain.
