AUDIO HEAD UNIT DEVELOPMENT BOARD

 

 

Raspberry Compute Module 3 based, full-featured development board focusing on audio-video purposes. There are many Raspberry based development boards on the market. On this one, many interesting features are available next to the commonly implemented ones. High resolution 7" IPS touchscreen, 4-channel audio amplifier with balance, LTE modem for internet connection, WiFi, 5pcs of USB ports, HDMI for external displays, infrared remote sensor and many else.

Using this board, students or well-experienced Linux software development engineers can realize their applications in a much faster way than earlier.
