[Necromant] is ready to dip his toes into the world of firmware development for everyone’s favorite WiFi chip, the ESP8266. Before that begins, it would be a good idea to make a nifty little breakout board for this chip. Here it is, a board with a USB to UART converter with board art that’s compatible with a toner transfer process.
Since this is just a board that turns USB into something the ESP8266 can understand, the most reasonable course of action would be to throw an FTDI chip in there and call it a day. We wouldn’t suggest that. Instead, [necromant] is using a Prolific PL2303HX. The RTS/DTR pins on the serial chip aren’t used, but only because the ESP8266 forums haven’t yet decided on how to connect them to the WiFi chip. GPIOs on the Prolific are broken out for some other projects [necromant] has in mind, with a userspace driver to make everything work.
[Necromant] is the creator of Antares, a build system for microcontrollers and a Hackaday Prize entry. He intends to make his build system compatible with this WiFi chip, just as soon as everyone else figures out an easy way to make it work.
