STWIN development kit - STEVAL-STWINKT1B
Hardware Overview
STWIN - SensorTile Wireless Industrial Node
The STWIN (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), wired RS485 and USB OTG connectivity.
