Purpose-built IoT node

The Heltec V3 ESP32 LoRa development board combines a dual-core 240MHz ESP32-S3 with an SX1262 LoRa transceiver for long-range wireless projects. It targets makers building Meshtastic networks, LoRaWAN sensors or smart-home and industrial control nodes. A .96in OLED and an 800mAh battery are integrated on the compact PCB.

Verify your toolchain and antenna plan

Confirm that your development environment supports the ESP32-S3 architecture and the CP2102 USB-to-serial interface for flashing. The board exposes an IPEX antenna port, so you must source a compatible antenna for the LoRa radio. Ensure your enclosure design accommodates the pre-soldered GPIO header and the Type-C USB connector.

Ruggedised enclosure with daily-use implications

The supplied N30 black case protects the board while keeping the OLED visible for real-time status. Type-C USB provides both power and serial access without proprietary cables. The 21dBm transmit power and -134dBm sensitivity (SF12) suit remote deployments, while the onboard lithium management circuit handles charging cycles for the 800mAh cell.

Questions about this item

Does the board ship with the OLED display, battery and case already fitted, or do I need to buy any of them separately?

The Heltec V3 board comes with the 0.96 OLED, an 800mAh battery and the N30 case included, so no extra parts are required to start.

Which LoRa chip version is on this board and what transmit power does it deliver?

It uses the SX1262 LoRa chip providing 21dBm transmit power and -134dBm sensitivity at SF12 for long-range links.

What does the 240MHz dual-core ESP32-S3 mean for real-world firmware like Meshtastic?

The 240MHz dual-core ESP32-S3 runs Meshtastic and LoRaWAN stacks smoothly while driving the OLED and managing Bluetooth 5 and Wi-Fi radios simultaneously.
