This user guide explains how to use the Isolated RS232 and RS485 Expansion Board for evaluating isolation and MCU products. It includes setup instructions, software demos via Simplicity Studio, and hardware details like jumpers and headers. The board enables communication and power transfer across isolation barriers using RS232 and RS485 protocols.
The guide covers connecting the board to MCU Starter Kits, loading demo code, and configuring jumpers for RS232 and RS485 signals. It also details supported applications in industrial, medical, and automotive markets, and lists key components such as Si88242ED-IS and ISL3332IAZ.
| Isolation Components | Si88242ED-IS, Si8631BB-B-IS1, ISL3332IAZ, UTB02268s |
|---|---|
| Supported Protocols | RS232 and RS485 |
| Connection Interface | 20-pin header for EFM8 and EFM32 Starter Kits |
