MFT-SEMA100 Flight Controller
The MFT-SEMA100 is a flight controller designed and produced by MFT Savunma ve Havacılık LTD. ŞTİ.
Features
- STM32H743 microcontroller
- BMI088 IMU
- BMP390 barometer
- LIB3MDL magnetometer
- MicroSD Card Slot
- 5 UARTs
- 12 PWM outputs
- 2 CANs
- 2 I2Cs
Physical
UART Mapping
- SERIAL0 -> USB
- SERIAL1 -> UART1 (MAVLink2, DMA-enabled)
- SERIAL2 -> UART2 (MAVLink2, DMA-enabled)
- SERIAL3 -> UART3 (GPS, DMA-enabled)
- SERIAL4 -> UART5 (GPS2, DMA-enabled)
- SERIAL5 -> UART7 (DMA-enabled)
- SERIAL6 -> UART8 (RX only)
Connectors
All pins are 2.54 mm Pin Headers
Power Connector
XT30-PW 5V Input for powering the board
RC Input
The default RC input is configured on the UART8 RCIN pin.
PWM Output
The MFT-SEMA100 supports up to 12 PWM outputs.
PWM outputs are grouped and every group must use the same output protocol:
1, 2 are Group 1;
3, 4 are Group 2;
5, 6, 7, 8 are Group 3;
9, 10 are Group 4;
11, 12 are Group 5;
Channels within the same group need to use the same output rate.
GPIOs
The numbering of the GPIOs for PIN variables in ArduPilot is:
PWM1 50 PWM2 51 PWM3 52 PWM4 53 PWM5 54 PWM6 55 PWM7 56 PWM8 57
PWM9 58 PWM10 59 PWM11 60 PWM12 61
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 are:
- BATT_MONITOR 4
- BATT_VOLT_PIN 19
- BATT_CURR_PIN 8
- BATT_VOLT_MULT 10
- BATT_CURR_SCALE 10
Compass
The MFT-SEMA100 has a built-in compass sensor (LIB3MDL), and you can also attach an external compass using I2C on the SDA and SCL connector.
IMU Heater
The IMU heater in the MFT-SEMA100 can be controlled with the BRD_HEAT_TARG parameter, which is in degrees C.
Mechanical
- Mounting: 55 x 56 mm, Φ4 mm
- Dimensions: 64 x 65 x 10 mm
- Weight: 15g
Loading Firmware
The board comes pre-installed with an ArduPilot compatible bootloader, allowing the loading of *.apj firmware files with any ArduPilot compatible ground station.
