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

I designed it using KiCad

Connector - J1 - 8 pin DIN connector footprint from CUI MD-80SM

WiFi Module - U1 - WeMos D1 mini

LED - D1-D4 - 3mm pth LED

IR Reciever - U2 - TSOP41xx

Buzzer - BZ1 - 12mm buzzer

Resistor - R4 - PTH resistor 100 ohm

Resistors - R1-R3 - PTH resistor 1K ohm

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
