Dual-Core LoRa & BLE Connectivity for
Mesh Networking: Built with ESP32-S3 and SX1262 chipset, this esp32 dev board supports WiFi, Bluetooth LE 5.0, and longrange LoRa communication. It works seamlessly with meshtastic and meshcore protocols, making it an ideal hardware foundation for building meshtastic devices and meshtastic node deployments in smart agriculture, industrial monitoring, or remote sensor networks. ^^ Efficient Power Management for
Field Use: Board draws <20A in sleep mode and includes lithium battery charging, overcharge protection, and solar input ( 4.46V ). Providing the same lowpower reliability for portable or offgrid setups such as wireless alarms, water meter reading, and mobile LoRaWAN nodes. Ideal for running a meshtastic node over extended periods. ^^ Ample Memory for
Complex Firmware: With 2MB PSRAM and 16MB Flash, this esp32 dev board handles multitasking, UI interfaces, and realtime packet forwarding for meshcore applications. When configured as a meshcore device, it can run custom LoRaWAN stacks or Meshtastic firmware ^^ Builtin OLED &
Expansion Interfaces: Onboard 0.96 OLED display, USB TypeC with ESD protection, SH 1.258P in GNSS port, and solar input header. These features allow a meshtastic node to display GPS coordinates or signal status directly, while the dual IPEX antenna connectors (LoRa + 2.4GH z) simplify external antenna upgrades. ^^ Universal Compatibility & Rapid Prototyping Features: Backward compatible with Heltec LoRa V3/V2 pinouts and fully supported by Arduino IDE, MicroPython, and ESPIDF. Heltec V4 dev board adds USBC with ESD protection, dual IPEX antennas, an OLED display, and expanded headers making it the ultimate esp32 dev board for meshtastic enthusiasts, meshcore experimenters, and IoT creators needing GPS, WiFi, BLE, and LoRa in one package.
