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