10 clocked RGB LEDs (APA102-compatible), 3.3/5 V input
The ET-D16 is built around the 10 × SK9822 5050 RGB, 8-bit colour + 5-bit global brightness, APA102 protocol. It connects over 2-wire clock + data (SPI MOSI + SCK) (up to ~15MHz) and is powered from 5V, up to ~600mA at full white.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Flicker-free lighting on camera
- POV and fast animations
- Status bars
