H01R00 is a smart RGB LED module based on Cree CLVBA-FKA-CC1F1L1BB7R3R3 RGB LED and STM32F0 MCU. It is part of the upcoming Hexabitz modular prototyping system.

• Use as a stand-alone smart RGB LED and easily control 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!

FAQ

Q: Isn't a 32-bit MCU an overkill for a smart LED module?

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.

Q: What level of soldering experience is required?

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.
