Summary
WiFi LoRa 32 V3 also called Heltec V3, durable IoT maker kit powered by the ESP32S3 MCU and SX1262 LoRa Node chips, intergrated three wireless communication ways ——LoRa、BLE、Wi-Fi，along with an on-board OLED display, it presents a robust, all-in-one solution.
Its superior RF design and stable, minimal system design ensure the product is ready-to-use and support
for development methods like Arduino, Platform IO, ESP-IDF, and MicroPython makes it beginner-
friendly. It is now widely used in well-known long-range wireless open-source projects such as
Meshtastic and Meshcore, serving applications in smart cities, smart farms, industrial control, and
security systems.
WiFi LoRa 32 (V3) supports the following development methods:
Compared to WiFi LoRa 32 (V3), V2 has made the following upgrades:

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 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.
