Introduction
The DM870 Core-2 module is a single-board networked media player module, based on BridgeCo’s
DM870 media processor, and enables fast product developments with ethernet, WiFi and USB
connectivity. The module connects to standard legacy components in various audio, video/LCD and
control formats. It runs from a single 5V power supply and creates all the necessary voltages on the
module. A stabilized 3.3V power is provided to the main board, to allow for further system cost
reduction.
