About the ElectraWiFiBoard PCB

ElectraWiFiBoard is an open source ESP8266 PCB design by itay7564, published on GitHub under the MIT license. It is a 2-layer board measuring 69.3 × 34.5 mm, with 13 components from 11 distinct parts.

Its main chip is the WeMos_D1_mini, from the ESP8266 family. Other key parts include the TSOP41xx. By type, the board carries 4 diodes, 4 resistors, 2 ICs, 1 transistor, 1 connector and 1 buzzer.

It belongs with the iot & wireless designs in this gallery.

From the project

PCB design for connecting an esp8266 to Electra AC's with the ElectraWiFi library

A PCB which enables connecting an Electra air conditioner to internet using a Wemos D1 mini esp8266 module

The circuit is based on the ElectraWiFi repository by giladger which contains code for this project

Thanks to Guy Eshel who prompted the design and helped with measurments

Thanks to giladger and the contributors of the ElectraWiFi repo which contains the code for this project

ElectraWiFiBoard: common questions

What microcontroller does the ElectraWiFiBoard use?

The ElectraWiFiBoard is built around the WeMos_D1_mini, from the ESP8266 family.

How big is the ElectraWiFiBoard PCB?

The ElectraWiFiBoard measures 69.3 × 34.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ElectraWiFiBoard?

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

Where can I download the ElectraWiFiBoard design files?

From the itay7564/ElectraWiFiBoard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ElectraWiFiBoard design in my own project?

Yes, under the terms of its MIT license, which itay7564 chose for the repository.

Can I test firmware for the ElectraWiFiBoard 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.
