GPIO and UART Expansion pHAT for Raspberry Pi

Add another TWO seral UARTs and another eight GPIO pins to your Raspberry Pi Zero (etc) with this GPIO and UART Expansion pHAT from PMD Way. 

The extra connections are provided with the onboard SC16IS752 which operates on the I2C bus. 

Great for debugging and controlling more stuff. pHAT arrives fully-assembled and comes with mounting hardware to bolt to your Pi. Raspberry Pi not included.

Features:

• Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+
• Onboard SC16IS752, expands 2-ch UART and 8 programmable GPIO through I2C, no extra pins required
• It is stackable up to 16 this modules by setting the address jumper, that means up to 32-channels of UART
• Onboard multiple LEDs for indicating the UART working status
• Reserved I2C control pins, allows to work with other control boards
