Measurement Computing Corporation announced the release of their MCC 152 voltage output and digital I/O HAT for the Raspberry Pi. Many DAQ users are creating systems around the Raspberry Pi platform, and the growing base of Raspberry Pi users is making single-board-computers more common in professional DAQ applications.

The $99 MCC 152 is equipped with two 12-bit, 0-5 V analog outputs with update rates up to 5 kS/s, 8x bidirectional digital I/O lines with 3.3V and 5V support that can be configured as input or output on a bit by bit basis. Each output bit can source 10 mA and sink 25 mA, and can be individually disabled.

Screw terminal connections are available for all I/O, and power is provided via the Raspberry Pi’s 40-pin GPIO connector. The DAQ HAT supports 0 to 55°C temperatures.

The open-source MCC DAQ HAT Library of commands in C/C++ and Python allows users to develop applications on Linux. The library is available to download from GitHub, and a comprehensive API and hardware documentation are also provided.
