An open source USB to UART converter based on the CH340C IC and designed in KiCad by Tecknologg. The board design and schematic is open source so do whatever you wish with it :) ...

This breakout board pairs an SP3485 RS-485 transceiver with an FT232RL USB UART IC to convert a USB stream to RS-485. The hardware is released under Creative Commons ShareAlike 4.0 International.

There’s a small little command line tool that will talk to the usual 1-Wire temperature sensors. Both the circuit and the tool work with the most common USB to UART adapters.

[Ted] has demonstrated using a common USB to serial adapter as an SDR transmitter. That’s right, using the cheap little UART adapter you’ve almost certainly got sitting in your parts bin right ...

Book Abstract: Data communication standards are comprised of two components: The "protocol" and "Signal/data/port specifications for the devices involved". The protocol describes the format of the ...
