satsha-ttl
After some time of buying expensive FDTI cables (about 20$ nowadays) and having the need to use several USB to serial converters for my Fab Academy students, I developed my own fabbable solution. satsha-ttl features a CH340G USB to serial chip and it is designed to be cheap, reliable and easy to be reproduced. It uses an LDO voltage regulator and a jumper to switch between 3.3V and 5V, both for power and logic levels of TX/RX.
