Arduino; 2. Micro Python; 3. Platform.io; 4. Espressif IDE; We strongly recommend using Arduino. We have complete technical support and provide complete LoRaWAN code for ESP32 Arduino framework. **Q: Meshtastic screen has a digital front-end issue?** A: 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” **Q: “LoRa Error”** A: It does not indicate device damage. Please disregard this phenomenon. The LORA ERROR occurs because it is running the factory default LORA testing program and cannot find another device running the same program. ## Frequently Bought Together - MakerFocus ESP32 LoRa V3 Development Board with 915 MHz Antenna Integrated WiFi Bluetooth SX1262 CP2102 0.96-inch OLED Display Type C for Meshtastic IoT Arduino Intelligent Scenes - 915MHz LoRa Antenna Indoor 3dBi Gain Omni SMA Male + IPEX Cable 2 Pcs - MakerFocus 4pcs 3.7V 3000mAh Lithium Rechargeable Battery 1S 1C LiPo Battery with Protection Board Insulated Rubber Tape and Micro JST 1.25 Plug for Ar duino NodeMCU ESP32 Development Board --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/295371242-esp32-development-board-wifi-bluetooth-lora-dual-core-240mhz-cp2102](https://www.desertcart.ro/products/295371242-esp32-development-board-wifi-bluetooth-lora-dual-core-240mhz-cp2102) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-04-24*
