[Open Source XRC Remote Control] Version 4.1 updated, the data is open source

Welcome to join the XRC group to learn more, QQ group: 1073485333 All PCB hardware, schematics, firmware, and shell files have been open sourced in the group file. If you like it, you can try to make it yourself. The cost is not cheap, about 400, it depends on the individual. strength.
3.3 update, the OTA update of the SD card firmware has been completed. It is convenient and fast to use the Bootloader to update the firmware.
Introduction video: Introduction video
XRC remote control is a multi-functional open source remote control based on the STM32F4 platform, with a full Chinese interface, 32 physical channels, 3.5-inch true color IPS capacitive touch screen, supports CRSF protocol, supports ELRS, Black Sheep, Siyigao The frequency head supports the Mavlink protocol, has a built-in simple MP ground station, supports UAV flight control parameter adjustment, supports image browsing, e-books, video playback and NES games, and gravity sensing.
