Micro version of the SP RACING F3 EVO flight controller for micro multirotor systems on collector motors with modern F303 chip that allows you to fly like a racing quad.
Features
Even smaller size and weighs only 2 grams
Allows you to connect up to 4 brush motors (up to 10A per channel)
Supports CleanFlight, BetaFlight firmware.
Supports SBUS, PPM, DSM receivers
Supports 1-2S system power supply (selectable by jumper, default is 1S, schematic in the picture below)
Serial port UART2, UART2, UART3, with external power supply output up to 500mA (e.g. for connecting FPV system, radio receiver or small LED light)
Built-in battery voltage sensor
Features
Chip: STM32F303CCT6
Accelerometer: MPU6500

Board thickness: 1.2mm
Manufacturer: Eachine
Weight: 2g
Receiver connection
SBUS - connected in UART2, to pins +5V, GND, and RX2 (SBUS signal). In the configurator tab, in the ports should be checked SerialRX on UART2, as well as in the configuration tab select SBUS connection RX_SERIAL.
PPM - connected to the connector UART2, to pins +5V, GND, and RX2 (PPM signal). In the configuration tab, in the receiver settings to select RX_PPM.
DSM - connected directly soldered into the DSM interface to the pins at 3.3V, GND, RX3. In the ports should be set SerialRX3 to UART3
Setting for CleanFlight
For correct operation of the controller and collector motors it is necessary to write the following command"set motor_pwm_rate = 1000" in the command line (CLI) of CleanFlight or BetaFlight, then execute the command"save" to save the settings.
maksim, Конкретно на этой микро версии платы нет выхода на пищалку. Светодиоды можно подключить простые, которые питаются на 5В (неуправляемые). 5В можно взять на плате как показано на схеме подключения.
maksim, Плата подерживает только 1S, потому индикатор и не нужен, колекторники уже при 3,6 В 1S еле тянут, посадить ниже 3 В в полете в принципе не возможно.
