HELTEC LORA 32 V3

ESP32-S3 • SX1262 • Meshtastic Ready

Heltec LoRa 32 V3 development board with protective case and blue 0.96 inch OLED display.

Build the ultimate off-grid communication node. The Heltec WiFi LoRa 32 (V3) is the undisputed classic IoT development board for makers, now upgraded with the powerful ESP32-S3 dual-core processor and the highly efficient SX1262 LoRa chip. Arriving with a protective case and a crisp 0.96" blue OLED display, it is the perfect plug-and-play foundation for smart cities, wireless meter reading, and open-source comms networks.

⚡ MAKER PRO-TIPS & COMPATIBILITY
  • Meshtastic Screen Fix: If your screen looks garbled in Meshtastic, simply go to: Radio configuration → Display → Override OLED auto-detect → select "SSD1306".
  • V2 vs V3 Code: Because the V3 uses the ESP32-S3 MCU, old V2 code is not directly compatible.
  • Simultaneous WiFi/BT: This board lacks external PSRAM; WiFi and Bluetooth cannot be used simultaneously.
  • Note: 3.7V Lithium Battery is NOT included (requires SH1.25 x 2 connector).

🛠️ Hardware Highlights

Next-Gen Processing Driven by the ESP32-S3FN8 (Xtensa 32-bit LX7 dual-core), capable of hitting 240MHz for demanding IoT applications.
SX1262 LoRa Node Exceptional range with a max receiving sensitivity of -136dBm and a max TX power of 21±1dBm.
Smart Power Management Features a Type-C USB interface with complete voltage regulation, ESD protection, and auto-switching between USB and battery power.
Open-Source Champion Native support for major community projects including Meshtastic, ESP32 Paxcounter, Disaster Radio, and Tiny GS.
