kidsbits blocks coding I2C 8×8 Dot Matrix module is fully compatible with kidsbits control board and Lego building blocks.
You can easily connect it to kidsbits control board for communication using an RJ11 cable without worrying about wrong wiring and damage.
What’s better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8×8 matrix.
But if simply use a microcontroller to control an 8×8 matrix component, you may need to use 8 rows plus 8 columns in total 16 IO ports.
To save more port resources of microcontroller, this module uses HT16K33 chip to drive an 8×8 dot matrix. Just need to use the I2C communication port of microcontroller to control the dot matrix, pretty convenient.
