TronXY Mainboard Documentation

Introduction[]

This is the place where you can find info about TronXY mainboards. Most of the pictures are from the community or myself. This is supposed to help people figure out how these mainboards are built and if anything could be salvaged / taken off them for other purposes, as well as finding connections and functions of certain modules.

TronXY CXYV6-191121/CXYV10-20210309 (STM32F446 based)[]

In early 2022 Tronxy has moved from F103 chips to F446 MCU chips. This board does not have any bootloader encryption and is able to flash via the SD card. The bootloader offset is 64k, and will flash any .bin file placed in a folder named "update". (this info is preliminary). There are are several variations on this board in the wild, some have 2 USB ports, and some have a 5th stepper driver installed.
