replacement for adafruit Qualia Bare Driver Board for the LP097QX1 display

[trose-neuro]

Hi all!

A hardware question - not directly Bonsai/Bonvision related: sadly, the Adafruit Qualia Bare Driver Board for the LP097QX1 display that many of us use for visual stimuli has been discontinued. We still have a few, but are looking for alternatives. Has anyone of you found a readily available replacement?

These should be equivalent, but we fail to get consistent responses from the vendor

This one I found - but did not order/test

Same for this one:

We like the original adafruit driver since it exposes a PWM pin for screen blanking - so an equivalent replacement would be very useful.

best wishes

Hi folks,

Sonya here from the Allen Institute. We had the same problem, so I made a fork of the Adafruit repository and made minimal changes to make the design manufacturable. I also ported the design to KiCAD since EagleCAD software is now deprecated.

The release with the breakdown is here:
https://github.com/AllenNeuralDynamics/Adafruit-Qualia-Driver-PCB/releases/tag/pcb0.2.1

Cheers!

Dear Sonya!

This is fantastic - thanks a lot! I'll definitely have this produced. Given the amount of triple screen VRs have have up and running in our network, this is a huge help!

Best
Tobias

You can also buy these from Max Hunter if you don't want to go through the trouble of sourcing production: https://www.maxhunter.me/ (previously research assistant in the Carandini lab, now maker of things)

Hey, I'm making an order of a bunch of these for some labs, let me know if you'd like any.

They're pretty poorly designed in general though, and I suspect it might be nice to redesign them if there's enough interest (especially folks using them for 2-photon gating).

Hi,
Did you end up ordering? If so, any spares available?

Hi, I just sold my last 10 boards yesterday. How many are you looking for?

Was looking for 1-2, but it all comes down to price and how you perceive quality compared to the available Chinese drivers.
