Raspberry Pi SPI Isolated Analog Input Board

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

RPi-GP40M A digital input/output board suitable for acquiring analog signals such as from sensor devices. 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. This product can also be used as a communication interface to collect sensor information such as temperature, humidity, pressure, magnetism, pH, acceleration, and displacement by integrating it into the Raspberry Pi CM3 carrier boards "RPi-CM3MB2/-PoE" and "RPi-CM3MB3".

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 for strong resistance to harness disconnection (RPi-GP40M) ■The analog input resolution of this product is 12bit / 500ksps (theoretical value), with voltage input ranges supporting ±10V, ±5V, ±2.5V, ±1V, ±0.5V (bipolar) and 0-10V, 0-5V, 0-2.5V, 0-1V (unipolar), with the input range configurable via software. Additionally, the board's jumper resistor settings allow for 4-20mA current measurement support ■The RPi-GP40 series includes one channel of open collector type digital output terminals (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
