UG274: Isolated USB Expansion Board User Guide The Silicon Labs Isolated USB Evaluation Board is a hardware plugin card for EFM8 and EFM32 Starter Kits (STKs). The Isolated USB EXP is intended to help demonstrate KEY FEATURES OR KEY POINTS and evaluate applications for Silicon Labs isolation, interface, and MCU products. Silicon Labs isolation products create a CMOS barrier to protect components while still allowing 20-pin headers for connection to EFM8 for communication and power transfer. Silicon Labs interface products offer various turn- and EFM32 starter kits key solutions for interfacing between different protocols. Software demos are available Software demos available in Simplicity and can be downloaded and run through Simplicity Studio. The demos are able to Studio send signals across the isolation barrier and the message be seen by the user on a ter- Power and communication over isolation minal. They also showcase Silicon Labs ISOVolt technology as the MCU is powered barrier across the isolation barrier. Jumpers for easy manual control of input signals Note: For full use and evaluation of the Isolated USB EXP a MCU STK is needed. Soft- ware examples are provided for two MCU STKs, the EFM32 Wonder Gecko Starter Kit EFM32WG-STK3800 and the EFM8 Universal Bee 1 Starter Kit SLSTK2000A. silabs.com Building a more connected world.
