I want to control a water pipe 100 metres from my pc. So I can use a solenoid connected to an ESP32 with Lora module. Another ESP32/Lora can connect to my pc via USB so I can use serial connection. So I want two ESP32 with Lora but I do not need the OLED. Is there a module without OLED? I am not good at soldering to join an ESP32 to a Lora module…Obrigado!

I have ordered 2 RFM95 433MHz so I will solder them to ESP32’s. Much cheaper than the combined unit.

Hi.
Those modules might be a bit difficult to solder, but yes, they are much cheaper.
Most boards come with a display.
This one doesn’t, but it’s not very cheap.
Regards,
Sara

Thanks, I had not seen that board. It looks like it has a great antenna. I am hoping I can use a simple wire (the right length) but I can experiment. Obrigado e bom fim-de-semana!

Thanks.
We used the module with the wire and it worked pretty well.
Thank you.
Have a nice weekend.
