This is a small and leight-weight controller for up to 4 RC peripherals
(such as servos) with a digital I2C interface.
The main purpose of this device is to provide a simple digital interface
allowing microcontrollers and other processing logic to easily control
cheap RC model making servos.
The device presented here provides an I2C bus connection (just 2 signal wires)
and allows to control up to 4 independent servos.
Although this device is called 4 channel servo controller, it can
control any RC peripheral with the usual pulse length modulation input, not
