I ran across their trackpad [1] last night; it uses the same Azoteq TPS65 module as the keyboard I just bought. Unfortunately the module's discontinued. [2, 3] I guess people have been going through stockpiles of these given that the last manufacturing run was 2 years ago, but I note the MNT Reform Trackpad is listed as out of stock...

I'm wondering what they'll do to replace it. You can still buy the IQS550 chip it's based on and apparently make a very similar PCB. [4] The black frosted glass seems like more of a challenge for most DIY keyboard makers, maybe not for MNT. The replacement project I saw recommended "2mm thick matte acrylic".

[edit: or maybe the TPS65 manufacturing restarted? mouser apparently has it in stock. [5] although that's the A unit without the surface.]

The trackpad in the MNT Reform Next is custom based on the Azotech IQS9150 IC from what I’ve seen in their firmware sources.

Not sure if that will be directly compatible with the MNT Reform classic discussed here though.
