The mini, DIY, ~$5 cost, ESP8266 based, high performance flight controller.
- Frames (Quad X)
- Betaflight contiguration tool compatible
- Receiver protocol (8 channel PPM)
- ESC protocols (PWM, Oneshot125, Oneshot42, Multishot, Brushed, Dshot150, Dshot300, Dshot600)
- Configurable Gyro Filters (LPF, Notch, dTerm)
- Blackbox recording (OpenLog serial)
- In flight PID Tuning
- Flight modes (ACRO, ANGLE, AIRMODE, ARM)
- Up to 2kHz gyro/loop in acro, 1kHz with accelerometer (level)
- MSP protocol interface
- Cli interface
- Resorce mapping
- Buzzer
- Lipo voltage monitor
- Failsafe
Hardware:
- Wemos D1 Mini board (D1 Mini Lite too, ESP-12 for experienced users)
- MPU6050 I2C gyro (GY-88, GY-91, GY-521 or similar)
- PDB with 5V BEC
- Buzzer and some electronic components (optionally).
Software:
Windows: download and unzip Espressif Flash Download Tools
After flashing you need to configure few things first:
- Configure pinout according to your wiring, especially pin functions, you can find more information in CLI Reference
- Connect to Betaflight Configurator and setup to your preferences,
- Test motors without propellers
- Have fun ;)
The rule of thumb is if you cannot change specific option in Betaflight Configurator, that means it is not supported.
