MCC 118 DAQ HAT Enables Up to 64-Channel Voltage Measurement on Raspberry Pi Boards

Measurement Computing Corp. (MCC) has recently introduced their MCC 118 DAQ HAT for Raspberry Pi which includes 8 analog inputs for voltage measurements between +/- 10V at a 100kS/s data rate. You can also perform data acquisition on up to 64 channels by stacking up to 8 MCC-118 DAQ HATs on top of a single Raspberry Pi board. The maximum throughput is limited to 320 kS/s.

  • 8x 12-bit voltage inputs
  • 100 kS/s max sample rate (320 kS/s aggregate for stacked
    boards)
  • ±10 V input range
  • Onboard sample buffers allow for
    high-speed acquisition
  • External scan clock I/O
  • External digital trigger input
  • Screw terminal connections
  • Up to eight MCC HATs are stackable on top of a Raspberry Pi board

The data acquisition / data logger systems based on the add-on board would run Raspbian (Lite) on the Raspberry Pi board, as well as a DAQ HAT library developed by MCC, and whose source code, and some C & Python samples can be found in Github, together with detailed documentation.

Compared to other DAQ solutions for Raspberry Pi, MCC explains DAQ Hats are validated designs with higher resolution and accuracy, as well as higher sampling rates, which should shorten time-to-market and reduce support costs associated with using non-validated designs.
