Summary
●WiFi LoRa 32(V3) is a classic IoT dev board designed & produced by Heltec Automation.
●Since its launch in 2017, it has been loved by developers and makers.
●Widely used in numerous excellent open-source projects and directly made into products for LoRa/LoRaWAN features.
●The newly launched V3 version has the same pin sequence as the V2 version and retains Wi-Fi, BLE, LoRa, OLED display, and other functions.
●It is the best option for smart cities, farms, homes, industrial control, house security, wireless meter reading, and IoT developers.

FAQ
A1: 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.
A2:
●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.
A3: You can find this type of socket by search “SH1.25 x 2”.
A4: Of course, you can contact our sales staff and provide your ideas.
A5: 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.
Q6: Failed to upload code
A6: Please try the following steps:
1.Try using a different USB cable.
2.Enter BootLoader mode. There are two methods to enter this mode:
●Hold down the PRG button, connect the USB-C cable, then release the PRG button.
●Connect the USB-C cable, hold down the PRG button, press the RST button once, then release
the PRG button.
