    [queued] USB DAQ with the Teensy

    Working with a senior instrumentation specialist, we have implemented a USB DAQ module using the Teensy 3.2, with analog circuits designed around the electrical characteristics of the Teensy ADCs and DAC. There is also a precision current amplifier that we designed to pair with the board, and the system with software, provides measurement into the pA and pF ranges. The control software is written in Python and provides a GUI and CLI.

    I have been using the system to characterize OLEDS and measure detailed electrical effects of surface contamination. In these studies I routinely clock the two ADCs and DAC together, at 200 kHz without data loss.

    If anyone is interested, please let me know. I am planning to make some extra copies of the boards.
