# TMOTOR F4
## Description
One of the main considerations while designing the TMOTOR F4 was to provide users the maximum amount of UARTs, as well as motor outputs, while retaining maximum efficiency, a careful choice of pinmap allowed to run 6-8 DSHOT motors off just 2 timers, while breaking out all the 6 UARTs that the STM32F405 provides.
Plug & play connectivity with most popular 4in1 ESCs.
## MCU, Sensors and Features
### Hardware
- MCU: STM32F405
- IMU: ICM-20602 or MPU-6000
- 6 DSHOT motors outputs, 8 by remapping UART6 as M7 & 8, using just 2 timers
- BMP280 SPI
- 6 hardware UARTs, UART5 with a controllable inverter for SBUS, USART1 with bidirectional inverter for FPORT/SPORT
- Onboard regulator supports up to 6S
- Dataflash blackbox
- External I2C port
- JST-SH 10 pin 4in1 ESC plug
