Description

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.

●It is the best option for smart cities, farms, homes, industrial control, house security, wireless meter reading, and IoT developers.

FAQ

Q1: Is V2 code compatible with V3?

A1: No, the MCU is different.

Q2: Can ESP32’s WiFi and Bluetooth be used at the same time?

A2: 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.

Q3: Meshtastic screen has a digital front-end issue?

A3: It’s caused by the meshtastic setting. Changing the default screen to SSD1306 can solve the problem.

The specific steps are as follows:

“Radio configuration”→”Display”→”Override OLED auto-detect”→”SSD1306”

Q4: What’s the battery socket type?

A4: You can find this type of socket by search “SH1.25 x 2”.

Q5: What development methods does it support?

A5: 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.

Q6: Can the onboard 2.4GHz antenna be replaced?

A6: The 2.4GHz antenna is a spring antenna, and there is no additional interface on the board for 2.4GHz wireless signals.
