USB to TTL module

Overview

The use of a micro usb interface solves the problem of modules purchased on Taobao being inconvenient for desktop use due to the DuPont cable not being long enough. It uses a CH340N chip and is smaller in size. All chip resistors and capacitors are packaged in 0805 for easy soldering. Switch between 3.3v and 5v TTL levels via switch.
