How many times has this happened to you?  Saturday morning, wake up early to throw together those parts that arrived during the week…frame, motors, ESCs, flight controller and more…can’t wait to fly this thing.  Rush it out into the back yard, power it up, add some throttle, and nothing…or worse, smack, an instant and violent

The Falcon F4 is a high performance STM32F4 based flight controller with the following features: STM32F4 Processor running at 100MHz Invensense MPU9250 gyro, accelerometer, and magnetometer Measurement Specialties MS5611 barometer Main port, Flexi Port, 8-pin Flexi-IO port 6 ESC / Servo Outputs Mounting holes: 30.5 x 30.5 mm Overall size: 36 x 36 mm Power: 120mA @

Board – CC3D The OpenPilot Revolution aka Revo is a board more tuned to Acrobatic flying or GPS based auto-piloting. It has three sensors, the MPU6000 SPI based Accelerometer/Gyro, the MS5611 barometric pressure sensor and the and the Honeywell HMC5883L three axis digital compass module. It also features a 16Mbit SPI based EEPROM chip. It

Board – RMDO The DoDo board is a clone of the SPRacingF3 board in terms of CPU pin mappings. See the SPRacingF3 documentation. Hardware differences compared to SPRacingF3 are as follows: Rev 1 and Rev 2: the CPU is the cheaper version of the F3 with only 128KB FLASH. Rev 3: the CPU is a

Board – Olimexino The Olimexino is a cheap and widely available development board This board is not recommended for cleanflight development because many of the pins needed are not broken out to header pins. A better choice for development is the Port103R, EUSTM32F103RB (F1) or the STM32F3Discovery (F3). Connections RC Input INPUT PA0 CH1 –

Board – Naze32 The Naze32 target supports all Naze hardware revisions. Revision 4 and 5 are used and frequently flown by the primary maintainer. Previous Naze hardware revisions may have issues, if found please report via the github issue tracker. Serial Ports Value Identifier RX TX Notes 1 USART1 RX / PA10 TX / PA9

Board – MotoLab The MOTOLAB build target supports the STM32F3-based boards provided by MotoLab. At present this includes the TornadoFC and MotoF3. The TornadoFC is described here: http://www.rcgroups.com/forums/showthread.php?t=2473157 The MotoF3 documentation will be provided when the board is available. Both boards use the STM32F303 microcontroller and have the following features: 256K bytes of flash memory
