# SPEDIX F4
|
|
|
|
## Description
|
|
One of the main considerations while designing the SPEDIX 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.
|
|
Timer design favors running multirotor and fixed wing alike.
|
|
Plug & play connectivity to SPEDIX and AIKON 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
