Product Description

Meshnology N35 - ESP32 LoRa V3/WiFi LoRa 32 V4 Development Kit – 3000mAh Battery, 863~928MHz Antennas, OLED Display, Case (HTIT-WB32LAF)

All-in-One ESP32-S3 LoRa Development Kit
This compact board is powered by the ESP32-S3FN8 dual-core processor (240 MHz) and integrates Wi-Fi (802.11 b/g/n), LoRa (SX1262), and Bluetooth 5 LE, making it ideal for smart city, wireless sensor networks, Meshtastic, and other IoT applications. Fully Arduino-compatible and developer-friendly.

Reliable Long-Range Communication
Equipped with the SX1262 LoRa chip, the board delivers up to 21dBm transmit power and -134dBm sensitivity, enhanced by built-in RF shielding to reduce interference. It includes both 863~928MHz SMA and IPEX antennas, ensuring strong and stable LoRaWAN connections.

Durable Protective Case with Integrated Battery
Housed in a tough N35 protective enclosure, the board features a pre-installed 3000mAh Li-ion battery that supports Type-C charging, automatic power source switching, and battery level detection. Safety features include overcharge, short-circuit, and ESD protection. A built-in 0.96-inch OLED display (128x64) provides real-time debug data and system status.

Developer-Friendly I/O and Compatibility
Features a CP2102 USB-to-Serial chip for smooth programming, along with rich I/O: ADC, I2C, SPI, UART, and capacitive touch sensors. Fully compatible with Arduino IDE and Raspberry Pi for quick prototyping and integration.
