MakerFocus ESP32 Arduino SX1276 LoRaWAN Development Board with 868/915MHZ Antenna

Product Description
ESP32 Arduino wireless stick lite is an IoT suite that fully supports the standard LoRaWAN protocol. (Exclusive) Supports the Arduino version of the ESP32 + LoRaWAN protocol routine provided by Heltec. This is a standard LoRaWAN protocol that can communicate with any gateway/base station running the LoRaWAN protocol (requires serial number activation, only the development of the company) The board is available, the serial number can be queried on this page);

Feature:
Micro USB interface with complete voltage regulator, ESD protection, short circuit protection, RF shielding and other protection measures;
Onboard 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 CP2102 USB to serial port chip, convenient for program downloading, debugging information printing;
With good RF circuit design and good low-power design (sleep current ≤ 30uA), it is convenient for IoT application vendors to quickly verify solutions and deploy applications;
