Raspberry Pi Isolated Analog Input Board

Isolated analog input expansion board connected to the GPIO 40Pin (SPI) of Raspberry Pi. Terminal block type.

A digital input/output board that is optimal for acquiring analog signals from sensor devices. The RPi-GP40T/RPi-GP40M is an isolated analog input and digital conversion board that connects to the GPIO 40Pin (SPI) of the Raspberry Pi. By connecting this product to the Raspberry Pi, it is possible to input analog signals from sensor devices and convert them into digital signals. By integrating this product with the Raspberry Pi CM3 carrier boards "RPi-CM3MB2/-PoE" and "RPi-CM3MB3," it can also be used as a communication interface to collect sensor information such as temperature, humidity, pressure, magnetism, pH, acceleration, and displacement.

Product Information

basic information

■Isolated analog input board to be mounted on Raspberry-Pi GPIO40Pin connector ■Equipped with 8-channel analog input ports in HAT board size ■The RPi-GP10 series offers two types of input/output terminals: a terminal block model (RPi-GP40T) for easy wiring and a MIL connector model (20pin) with a locking mechanism that is resistant to harness disconnection (RPi-GP40M) ■The analog input resolution of this product is 12bit / 500ksps (theoretical value), with voltage input ranges of ±10V, ±5V, ±2.5V, ±1V, ±0.5V (bipolar) and 0-10V, 0-5V, 0-2.5V, 0-1V (unipolar), which can be set via software. Additionally, it supports 4-20mA current measurement through jumper resistor settings on the board ■The RPi-GP40 series includes one channel of open collector type digital output terminal (common to both T and M models) ■The RPi-GP40M features one channel of digital input (5V/10kΩ pull-up) ■Sample source and guides for use with Raspberry Pi are available on RATOC Git Hub
