Description
Ultra small usb to uart (TTL)
This design contains the necessary peripheral circuits needed for the CH340E to work,
and all its pins are led out for future use.
This design also includes a three-color LED lamp .
Blue is used to indicate the power status, red And green indicate RX and TX
As shown in the figure, the PCB is composed of three parts, used to assemble the finished upper, middle and lower three-layer board, passing three 0.8mm thick PCBs through the copper foil on the top Layered window and tail pin connection, so that it can be normally inserted into the USB interface to achieve its function
