Esp8266-tiny breakout board
About the Esp8266-tiny breakout board
Esp8266-tiny breakout board is an open source ESP8266 PCB design by ezcGman, published on GitHub. It is a 2-layer board measuring 27.5 × 32.4 mm, with 14 components from 13 distinct parts.
Its main chip is the ESP-07, from the ESP8266 family. Other key parts include the AMS1117-3.3. By type, the board carries 5 resistors, 3 connectors, 3 capacitors and 2 ICs.
It belongs with the iot & wireless and dev boards & breakouts designs in this gallery.
From the project
A very small (29,9x26,9mm) ESP8266 breakout board with 5V support, proper screw terminal for power wires and required resistors and caps for the ADC input!
Its downsides are clearly the quiescent current of at least 5mA up to 13mA! There are also smaller LDOs (the AMS1117 is SOT-223), but with that screw terminal I wanted, it wouldn't matter anyways. If you want to change it, you're welcome to edit the PCB using KiCad :)

Esp8266-tiny breakout board: common questions
What microcontroller does the Esp8266-tiny breakout board use?
The Esp8266-tiny breakout board is built around the ESP-07, from the ESP8266 family.
How big is the Esp8266-tiny breakout board?
The Esp8266-tiny breakout board measures 27.5 × 32.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Esp8266-tiny breakout board?
14 components, from 13 distinct parts. The full bill of materials is listed on this page.
Where can I download the Esp8266-tiny breakout board design files?
From the ezcGman/esp8266-tiny-breakout-board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Esp8266-tiny breakout board design in my own project?
The repository has no license, so all rights stay with ezcGman. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esp8266-tiny breakout board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
