It was a good week for flight controllers from Poland. Few days ago ROTORACER showed his RACEBASE FC, yesterday Flyinglemon showed his AIR32 STM32F3 board. Comparing to RACEBASE F3 it is maybe less advanced in terms of integration, but not always more is better.
- integrated 5V step-down 600mA BEC compatible up to 6S
- SPI connected MPU6000
- 2 external UARTs
- Spektrum Satellite connector
- hardware FrSky S.BUS inverter
- VBAT, RSSI, WS2812 LED output,
- Boot tact switch
Board is supported by latest Betaflight 3.0 (still in RC phase) and special build of Betaflight 2.9.1.
Now, I'm waiting for a week of new F4 boards…
