New product: TTL232 - an RS-232 driver for those really old-school devices
Yes, they still exist... Every once in a while I come across some device that actually talks real RS-232. This is a pain because it means I have to pull out an old USB to RS-232 cable. Most electronics today expose UARTs (serial ports) at TTL levels of 3.3V or 5.0V. This is why the Nautilus USB UART features a switch allowing you to select between these two most common voltages. Simple and versatile I wanted something more versatile than a single-unit USB to RS-232 cable, so I went ahead and designed just the RS-232 to TTL part. The male pins accept...
