Why do we need Maker series products?
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.
WiFi LoRa 32 (V3) supports the following development methods:

Highlights
Onboard OLED Display
The integrated OLED display can be used to show some information such as systemstatus and parameters, making it convenient for users to directly use the entiredevelopment board for their own product design.
UsB Type C
The power supply, firmware download, and debugging interfaces adopt a moreuniversal USB Type C interface, making development work more convenient.
Plastic Shell
We also made a plastic shell as an optional accessory. Which provide basicprotection for the development board.
WiFi LoRa 32 is compatible with the following open-source projects:
ESP32 Paxcounter
Disaster Radio
Meshtastic
Tiny GS
…
We also provide a standard ESP32 Arduino LoRaWAN library:
Heltec ESP32 LoRaWAN
This library is already included in the Heltec ESP32 Arduino Framework by default.

FAQ
1.Can the onboard 2.4GHz antenna be replaced?
The 2.4GHz antenna is a spring antenna, and there is no additional interface on the board for 2.4GHz wireless signals.
2.Can ESP32’s WiFi and Bluetooth be used at the same time?
No, the WiFi LoRa 32 don’t have an external PSRAM, if your application need use Bluetooth and Wi-Fi at the 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.
6.Is V2 code compatible with V3?
No, the MCU is different.
