About the Breadboard PCB

Breadboard is an open source ESP8266 PCB design by amitesh-singh, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 100 × 100 mm, with 24 components from 11 distinct parts.

Its main chip is the ESP-12E, from the ESP8266 family. Other key parts include the AMS1117-3V3, L7805 and bboard_3rows. By type, the board carries 7 connectors, 5 ICs, 5 capacitors, 5 resistors and 2 switches.

It belongs with the dev boards & breakouts designs in this gallery.

Breadboard: common questions

What microcontroller does the Breadboard use?

The Breadboard is built around the ESP-12E, from the ESP8266 family.

How big is the Breadboard PCB?

The Breadboard measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Breadboard?

24 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Breadboard design files?

From the amitesh-singh/kicad-pcbs repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Breadboard design in my own project?

Yes, under the terms of its GPL-3.0 license, which amitesh-singh chose for the repository.

Can I test firmware for the Breadboard 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.
