The default method of powering the Raspberry Pi Touch Display 2 in the SmartiPi Touch Pro 3 is using the Raspberry Pi or HAT GPIO pins. This kit powers the Raspberry Pi Touch Display 2 and Raspberry Pi with the USB-C power supply. This is needed if you are using a HAT board without extended GPIO pins. This kit includes a panel for use with the large back cover, a panel mount micro USB cable, and a USB-C to USB-C/Micro USB splitter. Works with any USB-C power supply. Will disable the 5 amp mode when used with the Raspberry Pi 27W power supply. Compatible with the SmartiPi Touch Pro 3 large size back cover.
