Farnell Expands Range of Arduino Products with New MKR Shields

Hits: 6

The Development Distributor, Premier Farnell, has extended its embedded product offering to include four powerful and compact Arduino MKR Shields, designed to extend the capability and application of Arduino boards.

Featuring embedded connectivity and extremely low power consumption, the open source Arduino accessories are suitable for a range of battery powered IoT edge applications. The ENV Shield, RGB Shield and Therm Shield have a standard, modular design and are powered by a 32-bit Arm microcontroller. Integrated connectivity is Wi-Fi, GSM, NB-IoT, SigFox or LoRa.

The new products now available includes:

  • The Arduino MKR Motor Carrier: can be used with the MKR boards for prototyping. It can be used to connect up to four motors and sensors to control servo, DC and stepper motors also can connect actuators and sensors using the three-pin male headers.
  • The Arduino MKR ENV (Environmental) Shield: With its compact 61mm x 25mm design, 32g weight and an input voltage of 3.3V, the ENV Shield allows an MKR board to easily gather and store environmental data collected by a range of sensors. Sensors monitor atmospheric pressure, temperature and humidity, light intensity (LUX) and ultraviolet intensity (UVA and UVB). The shield comes with a microSD card reader and features a ready-to-use library, programmed to read values from different sensors to ensure smooth integration and data collection.
  • The MKR RGB Shield: is a development board that allows users to write message and add graphics from an MKR board. It can be plugged onto an MKR board without requiring soldering or special adapters. It measures 61.5mm x 27mm and has a 5V input and maximum current of 2.5V and is equipped with 84 LEDs for full RGB colour. The shield is controlled from the Arduino IoT cloud.
  • The MKR Therm Shield: has the same dimensions as the environmental shield. It can operate at high temperatures (200oC to 700oC) with an input of 3.3V to provide an extended range of temperatures from a type K thermocouple and a DS18Bxx digital one-wire sensor. The thermocouple can be used with or without a plug attached to the metal wires, using two connectors. There is also a MAX31855 thermocouple digital interface.

Hari Kalyanaraman, global head of SBCs for Farnell, said that the configurations were designed for developers and makers developing IoT applications across a variety of IoT projects, including industrial. “With a versatile mix of wireless connectivity and sensor options, the MKR series provides flexibility for engineers and makers looking to develop and deploy IoT applications easily using the Arduino ecosystem,” he said.
