2.2 Bluetooth® Low Energy Parallel 8080 Hardware Overview

The Bluetooth® Low Energy parallel 8080 project also uses the PIC32-BZ6 Curiosity Board. The LCD panel used is the maxTouch® Curiosity Pro Board. This display is equipped with the ILI9844 external controller. The 24-Bit Pass Through Graphics Card is used to interface with the display. For more information on the hardware requirements and setup, see the BLE and Parallel 8080 Interface Transparent UART.
