If you find faster, modern and powerful Arduino board, a ProDino MKR Zero V1 board is for you. You can do with it vary applications, it could be from home projects to industrial use. It also as a great educational tool for learning about 32-bit application development. The board is powered by Atmel’s SAMD21 MCU, which features a 32-bit ARM Cortex® M0+ core.
The ProDino MKR Zero V1 has 4 relays. The 4 Relays are a solution for driving high power loads that cannot be controlled by microcontroller’s digital IOs, due to the current and voltage limits of the controller. Each relay provides 2 pole changeover contacts (NO and NC). Relays are useful in switching on/off AC appliances like fan, light, motor or high current DC actuators like solenoid valve etc. Included four LEDs indicate the on/off state of each relay.
The 4 digital inputs are isolated. This is helpful for connecting ProDino MKR Zero to a system with a different ground and different voltage or noisy system. This electrically isolates a controller from the high-power system by use of an opto-isolator IC. This allows the low-voltage side to control a high voltage side. Great for use in noisy circuits where signal lines require electrical isolation. Four LEDs indicate the On/Off state of each input.
The ProDino MKR Zero board contains one GROVE Digital connector. The Grove System simplifies traditional electronics it consists of a base platform and various modules with standardized connectors. Each Grove module addresses a range of functions such as simple LEDs, buttons, switches to complex servo control, etc. With the combination with Grove modules, the project possibilities are endless!
Thanks that the ProDino MKR Zero board owns RS485, now you will be able to have a communication port for your RS485 devices! It will allow up to 32 devices to communicate through the same data line over a cable length of up to 1200m/4000ft. It is and the ultimate expansion that allows your board to connect to almost every legacy industrial system using serial connectivity such as industrial PLCs, controllers, drives and HMIs.
The RS485 can be use to turn old industrial systems like industrial machinery, heating systems and conveyors into new IoT devices. It supports high speed 500 Kbps in a short distance.
The ProDino MKR Zero contains more a micro USB connector and a reset button.
It is compatible with "Arduino MKR GSM 1400".
