Measurement Computing Corporation (MCC) and Data Translation (DT) DAQ products are now part of the Digilent family of test and measurement solutions. MCC and DT are leading suppliers of data acquisition solutions that are easy-to-use, easy-to-integrate, and easy-to-support.

The MCC 118 and MCC 128 DAQ HATs feature eight channels of analog voltage measurement for Raspberry Pi-based data acquisition systems. Each device has a maximum sample rate of 100 kS/s for taking single point or waveform voltage measurements. Up to eight MCC HATs can be stacked onto one Raspberry Pi - providing up to 64 channels of data and a maximum throughput of 320 kS/s.

MCC 118 features 12-bit resolution and 8 SE analog inputs with a +/-10V input range. An OEM version without screw terminal connectors is also available. 

MCC 128 features 16-bit resolution and 8 SE/ 4 DIFF analog inputs with the following input ranges (+/-10 V, +/-5 V, +/-2 V, +/-1 V). An OEM version without screw terminal connectors is also available. 

All DAQ HATs include C/C++® and Python™ examples and an open-source library. Comprehensive API and hardware documentation are also provided.

There are five devices in the MCC DAQ HAT Series. Models are available with voltage inputs, thermocouple inputs, IEPE-based sensor inputs, analog outputs, and digital I/O allowing users to configure multifunction, Raspberry Pi-based data logger solutions.

Raspberry Pi is not included with the MCC 118/MCC 128.

OEM/Embedded Customers- please contact our dedicated application engineer for volume pricing, OEM/board-only versions of these devices, and assistance with your application. Visit our OEM Board-only page for more product offerings.

The open-source MCC DAQ HAT Library of commands in C/C++ and Python allows users to develop applications on the Raspberry Pi using the Raspbian®/Raspberry Pi OS®. The library is available to download from GitHub. Comprehensive API and hardware documentation are available. The MCC DAQ HAT Library supports operation with multiple MCC DAQ HATs running concurrently. The library includes example programs developed in C/C++ and Python that users can run to become familiar with the DAQ HAT library and boards; source code is included.

    Easy to Use and Works Great

    Posted by CU1 on 26th Jan 2021

    I bought the MCC118 to go along with a MCC 134 and MCC 152 HAT for total automated experimental control of a power supply and associated pump equipment. Everything with a Pi base. The MCC118 HAT was easy to stack and also easy to use by copying pieces of the example code into a larger script.

    Amazing performance for the price

    Posted by Andrew on 21st Dec 2020

    We picked this up for a custom device we built to monitor and log variations in an optical signal. Our original plan was to try this out for prototyping and then go from there, but the performance was excellent and the API was great so we found that this was already more than enough for our application. Great product.

    Great idea

    Combining MCC linux driver support with a raspberry daqhat is a big win. Python code, inexpensive portable PC, and a solid inexpensive daq board surpasses the big corp proprietary lockin model !

    Excellent daq Hat

    Posted by Rocketman on 6th Feb 2020

    I bought the hat for acquiring 4 channels of analog data at 16k samples/s per channel .After installing the hat c-libraries, I was able to easily modify one of the given c-code examples and compile successfully. I was a bit skeptical, but I am now presently surprised. The raspberry pi processor cores didn't even get much load at all. It looks like most of the processing work was done by the hat hardware. I highly recommend this product. Thx.

    Great Hat!!

    Posted by Kawski on 22nd Jan 2020

    Works so well for so many applications. One project in the works going great, Just got another one for a second project. Great Support for someone new (Like me) to Python and the Raspberry Pi.

    Cool data logger

    Posted by RichH603 on 30th Jan 2019

    Getting the software and libraries isn't intuitive for people new to Raspberry Pi. Still working my way thru that. The board seems to be high quality, it fits perfectly, the hardware is great, and overall it just kinda cool. Once I figured this one out I hope to start using multiple hats.
