Description
This Multi-Functional Expansion Board is designed for use with both Raspberry Pi and Arduino. It is compatible with the Compute Module IO Board V3 from the Raspberry Pi Foundation and features a Raspberry Pi GPIO header for connecting a variety of Raspberry Pi HATs. The board also supports Arduino shields and has a 1-WIRE interface for connecting single-bus devices like DS18B20.
For I/O testing, the board features 4x keys, 4x LEDs, and 1x Buzzer. It also has an onboard USB HUB, allowing for connecting more USB devices. An IR receiver is available on the board for IR remote control. Additionally, the board has an onboard USB TO UART for serial debugging.
The sensor interface on the board allows for connecting various sensors, while the 10-bit ADC with 38KSPS and 11 channels (6 channels for Arduino interface, 5 channels for sensors) and 16-bit DAC with 2 channels provide accurate analog inputs and outputs. The onboard RTC is one of the most common and useful functions.
