64-bit expansion I/O board 'MPC-RAS64DIO' developed for Raspberry Pi.
The RAS64DIO is an expansion I/O board developed for the Raspberry Pi. The input and output signals are bidirectional buses, and can be set to input or output on a per-port basis via commands, totaling 64 bits for input and output. It is RoHS compliant. ◆ Features Input Section ◎ Input voltage range: 3.3V to 5V, CMOS logic signals All input signals can be selected as +5V pull-up or GND pull-down. (All ports are pull-up by default) Output Section ◎ Equipped with SN74HC574PWR Outputs a voltage of 5V and a current of 20mA (short circuit). Common Section ◎ Board size Same size as Raspberry Pi 3 MODEL-B and Raspberry Pi 2 MODEL-B ◎ Connection with Raspberry Pi Connects to the Raspberry Pi's expansion connector and communicates via I2C or SPI. ◎ When connecting to the Raspberry Pi's expansion connector, an intermediate board such as MPC-RASST may be required.
