TGR Jane V2 Me, gone through 3x MNK88 PCB over 2 years+
« on: Mon, 14 April 2025, 10:09:09 »
Hello, I have been using on and off a TGR Jane V2 Me since I got it around 2022. Over the course of this time, I have gone through 3 PCBs (MNK88). I had originally gotten 2 PCBs with the initial order and monokei was kind enough to replace one PCB at shipping cost when the first PCB shorted out. I have tried different configurations to pinpoint the culprit to no avail (O-ring mount, Top mount, usb connected to monitor, directly connected to desktop, mechmarket custom cable, regular usb cable). It seems the most common issue was an ESD after touching the case prompting the "usb disconnect/reconnect sound" from windows. Sometimes a column of keys would stop working and restart working after disconnecting and reconnecting the usb. Eventually, all PCBs ended up being completely dead. Another potential issue happened when disconnecting or reconnecting the usb cable (a column of keys would stop working after reconnecting the usb cable).

I contacted monokei to purchase a new PCB as i ran out of all the ones that were at my disposition. They sadly did not have any on sale so I decided to purchase a Galatea TKL Hotswap PCB hoping that it would work. the page states it has Overcurrent & ESD protection.

I have done extensive research on ways to diminish ESD but since only disconnecting and reconnecting the usb would also cause problems, I am unsure that ESD is the only issue.

Does anyone have tips on how to better protect my PCB?

I am currently using owlabs v2 screw-in stabilizers. I read stabbies could also be a source of short-circuiting.

Thank you!

while i have designed my own (keyboard) pcb, i am no hardware engineer, so take my statements with a good grain of salt.
what you describe sounds like bad pcb design/manufacturing.
if you find a proven pcb that fits and use the daughterboard it is designed for (esd protection could be on either pcb..), i think you should be good for a while.
the mounting style should not affect this, unless the mounting damages the pcb..
