  • STM32 F3 MCU
  • MPU6500 accelerometer/gyro sensor unit (via SPI bus)
  • 4x 5A dual channel brushed ESCs (Mosfets)
  • Direct programming connection via side USB
  • (*) serial connection for external DSM2/DSMX sat receiver (e.g. Spektrum SAT, OrangeRx R100 or Lemon RX)
  • Alternate PPM receiver connection (i.e. Deltang Rx31)
  • Hardware bind switch for easy binding
  • Boot switch for easy firmware flashing
  • Voltage monitoring LED or Buzzer
  • 5V out – buck/boost regulator for powering accessories
  • Motor connections oriented for self explanatory connection
  • Dimensions: 27x31mm (use thin FR4 material for weight savings)
  • Direct operation from an single cell lipo battery
  • All components arranged on the top layer

* Most Spektrum Compatible DSM2 satellites work out of the box. DSMX sat should also work with DSM2 protocol with default settings. (DSM2, 11bit, 11ms is preset).

NOTES: Battery Voltage monitoring on 1S powered machines is not very effective (and is disabled by default in Cleanflight F3 firmware).

Lost Model Alarm: A small Buzzer with a low current draw (=<20mA) can be used in place of the VMON LED. You can tie activation of this Buzzer to a switch on your Transmitter via the Beeper option, on the Cleanflight modes page.
