USB to Serial board came as a helping board for my another my project. I had to program a number of cheap Arduino Pro Mini clone boards in a row. The problem I was having was to mix up cable all the time. I decided to fix this issue once and for all by creating a simple USB to Serial interface board which will connect directly with Arduino Pro Mini correctly.

USB2Serial_CH340G_v1.2 is a simple USB to Serial board based on CH340G chip, created especially to fit well with Arduino Pro Mini boards.

Preview:

Schematics in PDF format

Features:

• based on very cheap CH340G chip
• locked pins for Pro Mini
• configurable for 5V and 3.3V

CAM files are available. BoM and PnP files for JLCPCB are available.

USB2Serial_FT232RL_v1.0 is a simple USB to Serial board based on FT232RL chip, created especially to fit well with Arduino Pro Mini boards.
