- MCU: STM32F411CEU6
- IMU: MPU6500
- Barometer: BMP280
- OSD: AT7456E
- Firmware:MATEK F411
- Brushing Motor Supports: 615 716 816 820 8520
- Battery input voltage: 1S - 2S (3.0V-8.4V)
1.We had upload the Betaflight / STM32F411 (S411) 4.2.0 firmware and config it ,you can use it directly without uploading firmware.
# version
# Betaflight / STM32F411 (S411) 4.2.0 Jun 14 2020 / 03:04:43 (8f2d21460) MSP API: 1.43
# config: YES
# board: manufacturer_id: MTKS, board_name: MATEKF411
How to upload firmware?
More information you can read here,https://www.uavbb.com/viewtopic.php?t=41
Download Betaflight firmware from here, http://blog.rctoysky.com/invoice/invoice//betaflight_4.2.0_STM32F411.hex
importand! Download the config file from here, http://blog.rctoysky.com/invoice/invoice//F4DC_config.txt
Please note that if you upload the diffrent version Betaflight firmware, the config file is not same,
you should know how to set the config file,otherwise the LED is not on.So, I suggest you don't upload the firmware and use it directly.

2.Set UART2 as receiver.
