The Arduino MKR WAN 1300 delivers LoRa low-power WAN connectivity, and the Arduino MKR GSM 1400 adds global 2G/3G communications capability. Both of the highly compact boards feature dimensions of only 67.64- x 25-mm, together with low power consumption, making them an ideal choice for emerging battery-powered IoT edge devices in the MKR form factor for applications such as environmental monitoring, tracking, agriculture, energy monitoring and home automation.
The two boards, which were formally introduced during Arduino co-founder Massimo Banzi’s talk at the Maker Faire in New York on Saturday, are also available for pre-order via the global online Arduino Store.
Offering 32-bit computational power similar to the Arduino MKR Zero board, the latest Arduino MKR WAN 1300 is based around the Murata LoRa low-power connectivity module and the Atmel SAM D21 microcontroller, which integrates the 32-bit low-power ARM Cortex-M0+ processor, 256KB Flash memory and 32KB SRAM. The board’s design includes the ability to be powered via either two 1.5-V AA or AAA batteries or an external 5-V input via the USB interface – with automatic switching between the two power sources.
