4 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.
5 Timer design favors running multirotor and fixed wing alike.
6 Plug & play connectivity to SPEDIX and AIKON 4in1 ESCs,
8 ## MCU, Sensors and Features
12 - IMU: ICM-20602 or MPU-6000
13 - 6 DSHOT motors outputs, 8 by remapping UART6 as M7 & 8, using just 2 timers
15 - 6 hardware UARTs, UART5 with a controllable inverter for SBUS, USART1 with bidirectional inverter for FPORT/SPORT
16 - Onboard regulator supports up to 6S
19 - JST-SH 10 pin 4in1 ESC plug
