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.
MCC 118 DAQ HAT key features & specifications:
- 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.
MCC 118 DAQ HAT is available now for $99 directly on the product page, and the company expects more data acquisition boards to be released later in 2018.
