Overview
The M5Stack NeoHEX is a hexagonal panel carrying 37 individually addressable WS2812C RGB LEDs. A single data line controls the whole panel, and each pixel supports 256 brightness levels for 16,777,216 colours.
Two input sockets at different angles and one output socket let several panels and LED strips be chained, while still allowing a separate power feed where a long chain needs more current. Six mounting ears and a milky white diffuser are included.

What’s in the Box
- 1 x NeoHEX unit
- 1 x milky white diffuser
- 1 x power consumption reference card
- 1 x HY2.0-4P Grove cable, 20 cm
Please Note
- A controller such as an M5Stack Core, ESP32 or Arduino board is not included.
- At full brightness the panel draws over half an amp. Power it from a supply that can deliver that, not from a microcontroller pin.
