Serial to Wifi board hacking

I’m having fun with my Olimex ESP8266 dev board. For ~5 Euro you get a 80 MHz processor, built in Wifi, a bunch of I/O, and “IoT” style libraries with a RTOS. This is the same chip that’s used on the serial to Wifi boards but with all of the I/O broken out. I especially like how they use half-holes on the edges to also make it PCB mountable.


So far I’ve only built the community run toolchain and loaded the blinky example onto it. The photo shows the boot mode switch, FTDI serial interface, and cables off to the 3.3 V supply.

Next step is to turn the LED on and off from a web form.
