usb to ttl ch340c version

Overview

A usb to ttl downloader based on ch340c, with common pinouts, supports two voltages of 5v and 3.3V, and uses a typec interface. The main USB to TTL converters on the market use USB connectors, but USB to TTL requires the use of Dupont cables. It is inconvenient to plug directly into the chassis, so it was changed to a TypeC port. It is relatively convenient to put the operation directly on the desktop. many. The power indicator light can be used to check whether 5v and 3.3V are smooth. In order not to dazzle the eyes, use a larger value resistor. Bend the pin as much as possible to reduce the overall size and avoid pricking your hands. A 6v, 0.5a (jump current 1A) self-restoring fuse is added to avoid accidentally inserting mobile phone chargers and other equipment. The computer USB port voltage is generally 5v, 0.5a.

Updated in 20211104, a 3D shell is added. See the attachment for the shell.
