🔴 Samson Go Mic Failed Repair - No.1139

[@JonnyFix]

I just compared a bunch of other CM chips and the pins don't match, may have been a custom production run. So far the chips I've got from ebay were legit, shame about the price.

I doubt the processor chip would do anything if the flash memory chip is faulty - or a connection issue between processor and flash chips.

Things to check, inside the USB socket.

Please note the incorrect spelling of Sampson, lol.

My god you are right !

[@simontay4851]

Maybe you could salvage a USB audio chip from a scrap board that has the same or similar pinout. Ive got an old USB audio interface that has a USB audio chip on it. I'll check what chip it uses.

Its a TAS1020B

[@NiHaoMike64]

Does the analog output still work?

[@TheDefpom]

I don’t know, it is put away now, possibly never to be seen again.

Program: void main() { if( runtime_age > EXPIRE_RUNTIME_AGE ) { // Ruin clock signal, set Clockpin high, halt system, die REG_CLOCKPIN = 0xFF; // Processor halted at this point, time to buy a new one ;-) } .............. }
