ME817EV BT817

Evaluation Board

Datasheet

1 Introduction

The ME817EV is a customer evaluation board for

Bridgetek’s 4th generation EVE chip, BT817. The

ME817EV is used to develop and demonstrate

BT817’s graphics, touch and audio functionalities.

The board is capable of supporting LCD panels

with 40-pin LVDS interface, or 50-pin RGB

interface. 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.

For a full list of the BT817’s features, refer to

the BT817_8 Datasheet.
