Display Interface Adapters
124-1570 B-LCDAD-RPI1 DSI to Raspberry Pi Connector Adapter Board
124-1571 B-LCDAD-HDMI1 DSI to HDMI Connector Adapter Board

The DSI to HDMI adapter board, part number B-LCDAD-HDMI1 is used for STM32 Development Boards or Discovery Boards. It comes with DSI input port and HDMI output port.

B-LCDAD-HDMI1 includes bridge chip ADV7533, therefore this board can support 2-, 3- or 4-lanes DSI video input data, S/PDIF, 2-channels I2S audio input data and HDMI v1.3 output port.

These boards have been designed for development purposes for the ARM Cortex STM32 MCUs.

STM32 carries external circuity such as transceivers, sensors, memory interfaces, displays and many more and are known as a reference design for application development.
