  Intro

  Control and automate your electrical appliances from long distances(Kilometres) without the presence of the internet. This is possible through LoRa!

  Hey, what's up, guys? Akarsh here from CETech.

  This PCB also has an OLED display and 3 relays which are connected to the ESP32. You can do anything with the code and control the relays using LoRa/WiFi/Bluetooth. So, in short, this project has an ESP32 which can give WiFi/Bluetooth functionality, LoRa module, OLED display and 3 relays. Possibilities with the code are endless. I have also added a prototyping area where you can add sensors or additional relays to the ESP32 which is also accessible.

  This is a type of part 2 of a project. So for any control system like this one you need a remote to control the things.

  I made a LoRa based remote which you can check out here: https://www.instructables.com/id/LoRa-Remote-Cont...

  In my case, I am using the remote and this controller together and they work like a charm!

  Parts

  Firstly as the main part, I used an ESP32 module from DFRobot. Attached it on the PCB using some male and female headers. I used an OLED display.

  For the LoRa purpose, I used an RYLR896. I highly suggest this module as it is very easy to use over UART using AT commands.

  You can find the parts below:

  1) ESP32 FireBeetle Module: https://www.dfrobot.com/product-1590.html

  2) Reyax RYLR896 LoRa module

  3) My PCB design: I have included the Gerber file below.

  For the last two parts if you have difficulty in finding them out you can message/email me and either I can help you find it in your area or I can ship them to you if you wish.
