Backlight LED current can be adjusted using dip switches. Capacitive touch screens can be connected to the board through a 10-pin or 6-pin FPC connector. An Audio filter and amplifier are included on-board, allowing a 1/8W speaker to be driven. Audio source can be supplied from the BT817, or through a line-in connector.

The ME817EV board supports 2 types of host controller: MCU with SPI/QSPI master, or USB host, selectable through dip switches. The SPI option of the board behaves as a SPI slave, and requires a SPI Master for proper micro-controller interfacing and system integration. The USB option of the board behaves as a USB High-speed device using the FTDI FT4222H, and requires control from a USB host through the Type-C connector.
