The Revolution is a full 10DoF flight controller board capable of stabilizing various aircrafts ranging from small racing miniquads to large FPV fixed wing models and aerial photography platforms.

Along side standard stabilization modes it also supports various GPS assisted modes and GPS navigation flight.

Hardware Description

CPU

Open

Main processor is a STM32F405RGT6 ARM Cortex-M4 microcontroller.

Sensor Suite

Revolution's 10DoF are provided by:

• Invensense MPU6000 digital MEMS Gyro/Accelerometer

• Measurement Specialties MS5611 Barometer

• Honeywell HMC5883L Magnetometer

Integrated 433MHz radio

Open

Integrated HopeRF RFM22B 100mW 433MHz radio can be used with an OPLink modem for wireless telemetry, configuration and control.

Dimensions

Open

36x36mm with 30,5x30,5mm hole spacing

Connectivity

Open

Powering the board

Board can be powered with 4,8-10V DC power supply, usually from one of ESCs integrated BECs or an external 5V BEC. The voltage used to power the board will also power any peripheral devices like GPS, Bluetooth modem,... connected to it.

All input/output (Rx, Tx, PWM, etc.) signal levels are 3,3V (5V tolerant)

All Vcc pins are can be used to power the controller and devices connected to it.

PWM Outputs 1-6

Open

These are PWM outputs used to connect servo motors and ESCs. Outputs 5 and 6 can also be configured as analog inputs

Supported protocols:

• Standard PWM with configurable rate from 50Hz to 490Hz

• PWMSync (PWM synchronized to the gyro sampling rate)

• OneShot125

Pinout:

FlexIO Port

It's primary use is as a receiver port compatible with PWM and PPM receivers, but can also be used to provide up to 6 additional PWM outputs, serial telemetry port, and two GPIO pins.

The connector used is a 10pin JST-SH

Pinout:

Main Port

This is a UART serial port with a programmable inverter on the Rx pin. It can be used to connect various serial devices such as GPS receiver, OSD, Telemetry (Bluetooth, OPLink, etc.), S.Bus receiver, DSM satellite receiver...
