LoRa alternative

[Dhali-YD4GXP]

Currently in my country there is no E22-400M33S LoRa IC, all of them are already in modules. Is there any alternative? Thank you

You can try to use another module supported by RadioLib, but you need to do wiring yourself, I do not have PCB for other modules as I do not own them. Out of the box supported modules are from E22- series with compatible pinouts and RA-01.

I found RA-01SH SX1262 800MHz in my country. can i use it? and what if i don't have BUSY pin on my LoRa?

I never tested this module, so I cannot guarantee that it is going to work. I'm using only E22-* modules with this project. RA-01 I tested with another project, while there is a place to solder it on this PCB, I cannot give any guarantees. Also, RA-* modules are only t00mW and have frequency drift on temperature changes, I do not suggest them, it is just waste of time and money to use them.

If you want to experiment with DV it might be better to use companion app https://github.com/sh123/codec2_talkie and then implement your own KISS modem on any module on bread board, I have two examples https://github.com/sh123/lora_arduino_kiss_modem https://github.com/sh123/nrf24l01_arduino_kiss_modem
