Sterling-LWB STM Expansion Board
USER GUIDE
3. Software Development with the Sterling-LWB STM Expansion Board
3.1 Required Equipment
To be used directly with the WICED SDK, the Sterling-LWB expansion board requires an STM32F411
Discovery Board. The board is plugged on to the CON1 and CON2 headers, and provides the Host MCU,
user I/O and sensors.
The Sterling-LWB expansion board requires a 1A +5VDC power supply to operate. The barrel connector
(J3) is configured for 5VDC center positive. J3 powers both the Sterling-LWB expansion board and the
attached Discovery Board. For access to the JTAG and USB-to-serial adapter on the Sterling-LWB
expansion board, attach a Windows PC via micro-USB cable to the micro-USB port on the Sterling-LWB
expansion board (J1).
