STWIN development kit - STEVAL-STWINKT1B
Hardware Overview
STWIN - SensorTile Wireless Industrial Node
The STWIN (STEVAL-STWINKT1 or STEVAL-STWINKT1B) is a development kit and reference design that simplifies
prototyping and testing of advanced industrial IoT applications such as condition monitoring and predictive
maintenance. The kit supports BLE wireless connectivity through an on-board module and Wi-Fi connectivity through
a special plugin expansion board (STEVAL-STWINWFV1).
