FAQ
12.4GHz Antenna
The default 2.4G FPC antenna is located on the side of the plastic screen bracket.
If you wish to use an IPEX-connected 2.4G antenna, you need to remove the inductor marked as ① in
the diagram below, and add a 0-ohm resistor (or other conductive metal or cable) at the position
marked ② to connect to the IPEX interface.
2What 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.
3What’s the battery socket type?
You can find this type of socket by search “SH1.25 x 2”.
4Can I order a version without the OLED display?
Of course, you can contact our sales staff and provide your ideas.
5Are V3 and V4 compatible?
They are compatible in most scenarios.
Since V4 uses the same series of chips as V3, features the same OLED, and has an almost identical
pin layout, V3 and V4 can be used interchangeably in the majority of cases.
However, due to the increased transmit power, the transmit power settings in some code may no
longer correspond directly to the actual output.
