Usage with VFD Modular Clock
The latest firmware supports the FLW Addon.
Usage with Arduino
Get our Arduino library from github!
Just hook up VCC, GND, SDA and SCL and run the simple example included in the library to see four letter words generated in the serial console.
Depending on the board and whether or not you have other I2C/TWI devices attached at the same time, you may also need to add pull-up resistors to the SDA and SCL lines (around 4.7k)
