Product Features

A/D converter board suitable for analog signal acquisition.

RPi-GP40T/RPi-GP40M are isolated A/D converter board that plug into
40Pin(SPI) GPIO connector on a Raspberry Pi.
This product can convert analog signal inputed from sensor device into digital signal.
Using in combination with Raspberry Pi CM3 carrier board [RPi-CM3MB2/PoE] [RPi-CM3MB3], it can be used as a communication interface that gathers information from sensor devices such as temperature, humidity, pressure, magnetism, pH, acceleration, displacement etc.

8ch Analog Input and 1ch Digital Output on HAT size board.

This product has 8ch anaolog input and 1ch digital output on HATboard(65mm x 56.5mm) designed for use with Raspberry Pi.

MIL connector model has digital input function.

RPi-GP40 series have 1ch digital open-collector output terminal.
RPi-GP40M also has digital input function(5V/10kΩpull-up).

Two models are prepared (Terminal block model and MIL connector model)

There are two different types of connectors on Rpi-GP40 series, one is terminal block model that is easy to connect wire, and another is MIL connector model(20pin) that has lock mechanism to avoid unpluging harness.

Resolution 12bit/500ksps, Changeable input voltage range.

Analog input resolution is 12bit/500ksps(theoretical value), and input voltage range can be set to ±10V/±5V/±2.5V/±1V/±0.5V(bipolar) 0-10V/0-5V/0-2.5V/0-1V(unipolar) with software.
Also electric current value(4-20mA) can be measured by mounting a resistor on board.
