ARM board

Cooperkit is a modular electronics platform. Each module has its own function, such as light sensing, wireless communication, etc. 

Cooperkit Button is finger-sized, which can be connected to I/O port of main board or externally disconnected to check the switch state so as to control ON/OFF of LED lamp.  

Cooperkit Buzzer is connected to the digital I / O port, when the output is low, buzzer will give a long sound. If it is connected to an analog pulse width modulation (PWM) output , the buzzer can produce a variety of tones, which can be made into the speaker of electronic organ.

CooperKit DHT11 digital temperature & humidity sensor features a digital temperature & humidity sensor complex with a calibrated digital signal output. Its single-bus operation, extremely small size and low consumption enable it to be used in HVAC, automotive, weather stations, dehumidifier and other applications.

CooperKit Hall Sensor measures the Hall Effect with A3144, the output of the Hall sensor turns on when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it switches low and turn off when the magnetic field disappears.

BeagleBone Black is an MSRP community-supported development platform for developers and hobbyists. Boot Linux in under 10 seconds and get started on development in less than 5 minutes with just a single USB cable.

RAK8211-NB iTracker combines NB-IoT+BLE+GPS+ 5 Sensors Development Board has BLE GPRS GPS three in one module perfectly solves the problem of data interaction and control in the outdoor environment and the three party platform.
