F3 based mini FC with built-in BEC, Betaflight OSD and an MPU 6000 IMU.
Betaflight Target: OMNIBUS
MPU6000 via SPI
Size: 27x27mm, M3 mounting holes at 20x20mm
BEC: Built-in PDB with 5V/3A output (so they claim, probably more like 1A)
Input Voltage: 2S to 4S
Output pins: 4x motor output pins, 1 x buzzer pins, 1 x LED pins
Supports PPM and serial receiver inputs
- There is an error on the silkscreen printing for the UARTs for Rx2 and Rx3. It's in the part that's hard to read...The correct pinout is below
- The pin marked RC is the same as RX3. If you use PPM you should use either of these inputs for your receiver. If you're using SBUS or other serial protocols, you can put it anywhere and select the corresponding port on the ports page of the configurator. This is an F3 processor so you don't need to worry about which ports are inverted for signal or telemetry (unlike the F4, the F3 can invert internally).
- The 2 pins marked vbat are joined to each other and just there for convenience in wiring other devices to battery voltage. Either one serves the purpose.
- On the multi-pin connector, the pin marked 5V is an output from the onboard 5V BEC - in most cases you won't use this wire. DO NOT put external voltage into this spot.
