I noticed this the other day, just in case it's of interest to anyone on this thread. | https://www.tindie.com/products/nsayer/ftdi-be-gone/ | FTDI-be-gone is a USB-to-serial adapter. The RS-232 variant has a DB9M connector on one | end and a micro-B USB connector on the other. The TTL variant has a 6 pin SIP header on the | end opposite the USB connector. Both have two LEDs - a red one to indicate transmitted data | and a green one to indicate received data. | The USB-UART chip is a Cypress Semi CY7C65213. Rather than use a proprietary device | driver to implement the serial port in the host, it relies on CDC class drivers supplied by the | OS. Unrelated - if you know someone who works with clocks, or in other ways has a natural affinity to even per second ticks, https://www.tindie.com/products/nsayer/crazy-clock/ could be quite a horrible/good present to get them depending on their sense of humour (just bought one for a clock repairing geek friend :-p) David
