Product features:

Microprocessor: ESP32-S3FN8 (Xtensa ® 32 bit LX7 dual core processor, 5-stage pipe rack structure, with the dominant frequency up to 240MHz).

SX1262 LoRa node chip.

C-type USB interface is equipped with complete voltage regulator, ESD protection, short circuit, circuit protection, RF shielding and other protection measures.

On board SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB/battery power automatic switching).

Integrated WiFi, LoRa, Bluetooth three network connection, vehicle mounted Wi Fi, Bluetooth dedicated 2.4GHz metal spring antenna, reserved IPEX (U.FL) interface for LoRa.

On board 0.96 inch 128 * 64 dot matrix OLED display can be used to display debugging information, battery power and other information.

Integrated CP2102 USB to serial port chip, convenient for program downloading and debugging information printing.

Support Arduino development environment. We provide ESP32+LoRaWAN protocol Arduino ® Library, which is a standard LoRaWAN protocol and can be used to run the LoRaWAN protocol with.

The new V3 version has the same pin sequence as the V2 version, and retains Wi Fi, BLE, LoRa, OLED display and other functions.

It is the best choice for developers of smart cities, farms, homes, industrial control, house security, wireless meter reading and the Internet of Things.

Good RF circuit design and low power consumption design.
