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,
