Can HNers point toward a purpose-built system-on-a-board for data acquisition tasks? I keep seeing improvement in compute capability with Arduinos, RPis, BeagleBoards, etc. , but no movement in ADC precision.
Arduinos are wonderful for handing off to a student for a quick DAQ job, but invariably we require higher precision once they get things working, which requires additional engineering from our end.
Price <$100, 4+ 14-16-bit ADCs at 1-2 kSamples/s, 2+ 10+-bit DACs, reasonably stable clock?
- harshreality 12y agoNothing at that price I can recall, but you're looking for a watered-down Red Pitaya? (A single board doesn't have enough 14 bit inputs, but in all other ways, particularly frequencies, it exceeds those specs?)
- ISL 12y agoReally watered-down, yeah. It might be more appropriate to think, "arduino with higher-resolution inputs". It's really the Arduino ADC resolution that is a major headache for us.
- mty312 12y agoCypress PSoC5? 1x20bit and 2x12bit, but at sample rates far higher than you are looking for. Powerfulboard.com and moeller.io both make proto boards for them.
