ESP8266 Breakout Board

Recently, I purchased an ESP-07 module of ESP866 Wi-Fi SoC. ESP8266 is a super awesome, Arduino compatible, SoC with 80 MHz microcontroller, 512 KB of flash, 40 KB of RAM and integrated Wi-Fi in a single chip. All that under INR 500/- (USD 8). Neat eh?

So, when I purchased my first ESP-07 module, I was super excited for it to arrive. The close-up pictures of the Wi-Fi module on the eBay listing didn't do justice to it's actual size. At little bit over 16mm X 20mm, it was really small. And at 2mm spacing between it's pins, it was no way breadboard friendly. While, I could hack the module on a GP(General Purpose) PCB, it wasn't a good solution on a long run, if I were to develop actual products on it. So, I designed a simple breackout board that will break the 2mm pitch pins to breadboard friendly 2.5mm(0.1") pitch. I also added a 0.1 uF and a 100 uF capacitor to it, just in case there was some noise or current consumption peaked. Well, you don't have to solder them if you don't want. 

At first, I though that I'd add a dedicated regulator, some buttons and other things to this breakout board but not all of my project would have same requirement and sometimes, the whole project may have it's own regulator. So, to keep it simple, I just broke out all the pins.

The first batch is on it's way from OSH Park and hopefully will get it by month's end. 

If you want your own breakout board, you can order them using this link. Please note that, I cannot guarantee the accuracy of my design and if you purchase them, purchase and use them at your own risk.
