Board

I wouldn't bother replacing R1 or C1, I'm sure they're fine.
D1 is a BAV74 dual diode w/ common cathode.

U1 is a TPC6201, but it's obsolete. So use FDC6561AN as a replacement part.

Edit: But if you want to replace C1, it's a 100nF 0603
R1 is a 15K 4-resistor array. Example https://www.digikey.ca/products/en?keyw ... B-38V153JV

Thanks Fraser,

Was thinking too about the conensator and the resistant that might not be damaged.

I have ordered the mentioned components. Hope this will repair the boards.

Best regards,
Ed

Hi Phidget team!

I have repaired it and its working again. Replaced U1, the FET mentioned above, which is a very sensitive ESD Device.

Thanks for all and best regards,

Ed
