MKR WINDY is an Arduino MKR1000 form factor board based on the Midatronics WINDY Module, an IoT module with onboard uFL connector based on the ST Microelectronics STM32WL, System-On-Chip integrates both a general-purpose microcontroller and a sub-GHz radio on the same chip. Built on an Arm® Cortex®‐M4 core architecture, STM32WL microcontrollers also support multiple modulations – LoRa®, (G)FSK, (G)MSK, BPSK – to ensure flexibility in wireless applications with LoRaWAN®, Sigfox® or any other suitable protocol in a fully open way. The windy module features a sub-GHz radio based-on Semtech SX126x to meet the requirements of a wide range of Low-Power Wide Area Network (LPWAN) wireless applications in industrial and consumer Internet-of-Things (IoT).

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.
