Description

The MicoAir405 v2 is a new cost-effective flight controller runs Ardupilot&INAV firmware, This is the first one which combine the STM32F405 with the high performance IMU sensor BMI088, allowing the flight controllers to have top performance and an attractive price at the same time.

The BMI088 is a high-performance 6-axis IMU sensor that comes from Bosch®, its excellent temperature stability and vibration robustness far exceed similar products on the market, making it particularly suitable for drones and robotics applications.

The MicoAir405 v2 also integrates a high-performance barometer: spl06, and OSD chip: AT7456E, 2 DC-DC channels to provide 5V-3A and 9V-2.5A power output. These characteristics make this controller particularly suitable for long range FPV drones.

Specifications

  • MCU: STM32F405RGT6, 168MHz, 1MB Flash
  • IMU: BMI088
  • Baro: SPL06
  • OSD: AT7456E
  • MicroSD Card Slot
  • 6x UART
  • 10x PWM
  • 1x I2C
  • 1x SWD
  • 2x ADC (VBAT, Current)
  • USB Type-C
  • BEC 5V 3A output (for controller, receiver, GPS, optical flow or other devices)
  • BEC 9V 3A output (for video transmitter, camera)
UART Mapping
  • SERIAL0 -> USB
  • SERIAL1 -> UART1 (DMA-enabled)
  • SERIAL2 -> UART2 (DJI-VTX, DMA-enabled)
  • SERIAL3 -> UART3 (GPS)
  • SERIAL4 -> UART4 (DMA-enabled)
  • SERIAL5 -> UART5 (ESC Telemetry)
  • SERIAL6 -> UART6 (RX6 is inverted from SBUS pin, no DMA on TX6)
RC Input
The default RC input is configured on the UART6_RX inverted from the SBUS pin. Other RC protocols should be applied at other UART port such as UART1 or UART4, and set the protocol to receive RC data: SERIALn_PROTOCOL=23 and change SERIAL6 _Protocol to something other than ’23’
 
OSD Support
The MicoAir405v2 supports OSD using OSD_TYPE 1 (MAX7456 driver).
 
VTX Support
The SH1.0-6P connector supports a DJI O3 Air Unit connection. Pin 1 of the connector is 9v so be careful not to connect this to a peripheral requiring 5v.
 
PWM Output

The MicoAir405v2 supports up to 10 PWM outputs.

Channels 1-8 support DShot.

Channels 1-4 support bi-directional DShot. PWM output share grouped and every group must use the same output protocol:

1,2,5,6 are group 1

3, 4 are group 2

7,8 are group 3

9,10 are in group 4

 
Battery Monitoring
The board has a internal voltage sensor and connections on the ESC connector for an external current sensor input.
The voltage sensor can handle up to 6S LiPo batteries.
The default battery parameters(for Ardupilot) are:
  • BATT_VOLT_PIN 10
  • BATT_CURR_PIN 11
  • BATT_VOLT_MULT 21.2
  • BATT_CURR_SCALE 116.5

Compass

The MicoAir405v2 does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL connector.
 

Physical

  • Mounting: 30.5 x 30.5mm, Φ4mm
  • Dimensions: 36 x 36 x 8 mm
  • Weight: 9g
