same time, you can look into this product: Heltec Wireless Bridge.
3.What development methods does it support?
Arduino
Micro Python
Platform.io
Espressif IDE
We strongly recommend using Arduino. We have complete technical support and provide complete LoRaWAN
code for ESP32 Arduino framework.
4.What’s the battery socket type?
You can find this type of socket by search “SH1.25 x 2”.
5.Can I order a version without the OLED display?
Of course, you can contact our sales staff and provide your ideas.
