MKR Stormy is an Arduino MKR1000 form factor board based on the Midatronics Stormy Module, an IoT module with onboard PCB antenna and uFL connector based on the ST Microelectronics BLUENRG-LP, a very low power Bluetooth Low Energy (BLE) single-mode System-On-Chip. Built on an Arm® Cortex®-M0+ core architecture, BLUENRG-LP can run the user application code.

The stormy module offers excellent RF performance and the integrated high-efficiency DC-DC converter keeps the ultra-low-power characteristics and improves the sleep mode current consumption allowing a further increase in the battery lifetime of the applications.

The module is totally open and can be easily and quickly programmed with ST software by UART, virtual USB or with the ST-Link by SWD port.
