Used the board successfully with atc1441 CH559sdccUSBHost project from github to handle joystick input.
The only minor issue with my boards is that the printed io silkscreen seem to be one pin off toward USB port side of the board. For example Uart at pin P3.1 (tx) and P3.0 (rx) must be plugged near io silkscreen P3.0 and P4.7
