Open Pilot EE 587

3. Copter Control vs. Revolution
Two boards that both are compatible with same ground software
Both cater to the open source community
Open Pilot strives to make technology accessible by keeping costs down through a non-profit operating strategy

4. Copter Control STM32-bit microcontroller with 128KB Flash and 20KB RAM
4MB EEPROM
3-Axis gyros and 3-Axis accelerometer
36mmX36mm 4 layer PCB
Plug and play USB interface, no drivers required
Spektrum Satellite support
Futaba S-BUS support
Open Pilot EE 587

5. Copter Control continued
6 PWM input channels or combined PPM, 4 PWM output channels
10 PWM outputs for servos
Also has an updated version “CC3D” with minor updates that are said to improve performance
