H01R0x is a smart RGB LED module based on Cree CLVBA-FKA RGB LED and STM32F0 MCU. It is our first and most beloved module as it was used to test and develop most of Hexabitz backend!

  • Use this module as a stand-alone smart RGB LED and easily control it via a Command Line Interface (CLI).
  • Firmware has embedded on / off / toggle, PWM, dimming and color sweep functionality.
  • Program advanced C code with our easy-to-use APIs.
  • Connect many H01R00 modules together and build interesting flat and curved boards with any configuration you imagine!
  • Send commands to a single LED, a group of LEDs or broadcast to all of them at the same time.
  • Connect to external hardware or combine with other Hexabitz modules!

Frequently Asked Questions

A: Yes! But all Hexabitz modules -whether it’s a complex Ethernet or IMU or a simple LED- share same backend hardware and software. This what gives the platform its unmatched modularity and scalability. Cortex-M0 MCUs are small, cheap, power-efficient, yet capable of really wonderful things. Having an embedded MCU provides a cheaper and more compact alternative to connecting an LED breakout with an external controller.

A: Hexabitz are designed for the absolute soldering beginners! The edge pads are large and easy to reach and anyone with basic knowledge of soldering can assemble a flat array. Curved and spherical arrays require more training but can be made easier with 3d-printed fixtures.
