Serial Expansion HAT for Raspberry Pi

Description of Serial Expansion HAT for Raspberry Pi:

This Serial Expansion HAT provides a 2-channel I2C and UART interface with 8 programmable GPIO Pins where you can connect more accessories and add-ons. To do more things with this Raspberry Pi Serial Expansion HAT, we added more slots and there are 8 programmable GPIO pins where you can connect more accessories and add-ons.

Features of Serial Expansion HAT for Raspberry Pi:

• Raspberry Pi 40P IN standard GPIO extension header, support Raspberry Pi series boards: Zero/Zero W/Zero WH/2B/3B/3B+/4B.
• SC1618752 on board, extends the 2-channel UART and 8 programmable GPIO via 12C, no need for additional pins
