Product description: Serial Expansion HAT - UART, GPIO expander SC16IS752 for Raspberry Pi - SB Components SKU14873
Serial expander in form of HAT overlay for Raspberry Pi minicomputers equipped with 40-pin GPIO connector. Overlay is based on SC16IS752 chip, which extends Raspberry Pi with two additional UART serial interfaces and 8 programmable GPIO via I2C. There is also a 40-pin male goldpin connector on the module, which allows up to 16 overlays to be connected, equipping the minicomputer with up to 32 additional UART channels. The board also has LEDs to indicate the status of UART operation and pins to connect to a module other than the Raspberry Pi with an I2C interface.
The UART expander as an overlay for Raspberry Pi, minicomputer can be purchased separately.
Main features of the expander
- Standard Raspberry Pi 40-pin GPIO connector
