Neuropixels-1.0 Headstage¶
The ONIX Neuropixels-1.0 Headstage is a serialized, multifunction headstage targeting Neuropixels 1.0 probes.
Two Neuropixels 1.0 probes
A BNO055 9-axis IMU for real-time, 3D orientation tracking
Three TS4231 light to digital converters for real-time, 3D position tracking with HTC Vive base stations
An Intel MAX10 FPGA for real-time probe data correction (offset removal and gain correction) and data arbitration
Coaxial Link¶
For details on data serialiation and headstage gateware, have a look at the Coaxial Data Serialization & Power page, which describes how coax headstages operatate in general terms. The Neuropixels-1.0 Headstage has the following coaxial link properties:

Important
*The headstage includes an undervoltage and overvoltage lockout circuit that will only allow it to turn on when the proper link voltage is present headstage. If the headstage is not turning on, make sure that the voltage at the headstage itself is within the valid range
