This means they can both use the same firmware (Intan's 'Rhythm' USB/FPGA interface), and that the same FPGA can be used with either system. 8 digital-to-analog converters (for real-time audio monitoring and signal generation)īoth the Intan evaluation boards and our acquisition boards are powered by the Opal Kelly XEM6010 FPGA development board.8 analog-to-digital converters (separate from the converters on the headstages).12-wire cables that can be daisy-changed up to 10 meters (available from Intan for $175 per 3-foot length).4 headstage connectors (for a total of 128 channels of data acquisition when using 32-channel headstages).

32-channel headstages with 36-pin Omnetics connectors (available from Intan for $745 each).compatibility between acquisition boards, headstages, and software.Both the Intan RHD2000 Evaluation System and our new acquisition systems will feature: We worked with Intan to come up with some of the specifications for these boards, and will also adopt those standards for our own hardware. If you've been following the latest updates from Intan Technologies, you know that they've recently released an evaluation system for their RHD2000-series chips. Open Ephys RHD2132-based acquisition system Read on to find out about our plans for distributing these boards.

The design for our new acquisition board can be viewed on our GitHub site, with a full bill of materials on Google Docs. Since the last newsletter, we've made significant progress updating our hardware to incorporate the new digital chips from Intan.
