Complete pixhawk accessories set includes External RGB led, I2C Splitter and PPM Encoder module.
A handy unit for adding an external USB/LED port to any of the vehicles. Use the 4 position DF13 cable to connect to the splitter module to set up a bright multicolor LED and a convenient USB port.
The PPM Encoder v2.0 plugs into the PWM servo output ports of any R/C receiver and encodes them into a PPM pulse suitable for many autopilots (e.g. Pixhawk). Modifications to the R/C receiver are not necessary. The whole project is based around the ATMEL ATMEGA328p AVR processor and all timing is done within interrupts so accuracy and stability is optimized.
The I2C splitter expands the I2C port to allow up to four additional peripherals to connect to Pixhawk. Use the 4-wire cable to connect the I2C splitter and add a compass module, external LED, digital airspeed sensor, or other peripherals to your vehicle.
