Connect the project to your laptop or phone and then chat between the devices without internet or SMS using just LoRa.
Hey, what's up, guys? Akarsh here from CETech.
This PCB also has a display and 4 buttons which can be used as a remote control for some device as well. You can do anything with the code design your own UI. So, in short, this project has an esp8266 which can give WiFi functionality, LoRa module, 1.8 inch TFT display, 4 push buttons for making a UI. Possibilities with the code are endless.
It can be connected to your smartphone or any computer and it makes that device LoRa-enabled messenger. Now when that will be done you would be able to message any other device using the same LoRa messenger. This all is done without the presence of 4G/LTE/3G/GSM/WiFi/SMS. Which I have done in an earlier project which you can find here: https://hackaday.io/project/164090-lora-messenger-for-two-devices-for-distance-up-to
Firstly as the main part, I used an ESP8266 module with a breakout board. Attached it on the PCB using some male and female headers. I used a 1.8 inch TFT SPI display, TP4056 module for battery charging and protection and an old mobile phone battery.
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:
3) TFT display
6) My PCB design
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.
