This is a tiny ESP8266 breakout board. I made it because the small breakouts I bought took up the entire breadboard and didn't include basic pullup/pulldown resistors.
This repository includes a branch with an even tinier version that is smaller than an ESP8266 12E. It's the size of the 12E minus the antenna, and it includes the voltage regulator and all the capacitors and resistors the ESP8266 needs to boot, but it doesn't include through-hole connectors (so you will have to solder wires directly onto the ESP8266 contacts).
It's for when you really really need as much space as you can. Fabricate it at 0.4mm thickness and enjoy.
If you just want to buy the PCB directly, here's a paneled v1.4 version from Dirty PCBs, which includes 40 breakouts for $14. Note that the boards come without components, and you'll have to solder them yourself. You'll need:
- 0805 SMD 10k Ohm resistors
- 0805 SMD 10 uF capacitors
- SPX3819M5-L-3-3 TR 3.3V SMD LDO
- Male pin headers (optional)
If any of the links above aren't working, just search your favorite site for the components or visit your local electronics shop, they should have all of these.
You can use these ESP8266 versions with this PCB:
- ESP-07
- ESP-12
- ESP-12E
- ESP-12Q
- ESP-12F
- ESP-14
Use the board however you want, it's under the BSD license, here's what it looks like:
