MKL62ST-DT

LoRaWAN® Development Kit

MKL62ST-DT is a small and open source IoT development board specially designed for MOKO LoRaWAN module MKL62BA. The low-power SMT32 chip is used as the external MCU,and it integrated Sensirion STH30 temperature and humidity sensor on board. By running a demo application firmware provide by MOKO can quickly familiarize the working of LORA network and see the temperature and humidity sensor data on the LoRaWAN network server.

Product Features

> Has support for standard LoRaWAN-based protocols
> Anti-surge and anti-reverse connection
> Provides a lithium-ion battery connection interface, along with an integrated lithium battery charge and discharge management circuit
> Offers SHT30 sensors, switches and LED

> Its Interface (Peripheral) includes UART, GPIO, ADC, I2C, and Near Field Communication (NFC)
> Compatible with Arduino NANO interface
> CP2102 USB-UART chip for downloading programs and printing debugging information
> Provides an SMT32 and LoRaWAN-Based module serial port program interface
