Which firware must uploaded on this firware?and how must do it?
Does  stm32 has  bootloder itself

You upload the software the same way you do with Gotek drive.

What value are the resistor packs used, it doesn't say so on the schematics.... Also what value is 1n1000v capacitor?

sundbyk Reply

The resistors are 1K.
The C7 is 1nF 1000V. It will remove any static dischanges when inserting into the USB port.

@sundbyk Thanks for the clarification, I have one more question, all the Rotary Encoders I see need 5v, however the pinheader on your board delivers 3.3v, would it not be better to route that pin to the 5 v instead of 3.3v?

sundbyk Reply


The rotary encoder does only have pullup resistors.
It is only used for to pull the signal high for the MCU with uses 3V3.

I build the board.
The microcontroller and ls07 get too hot when I connect it to usb and before it burn i diconnect from usb
Do yourself build and test the board?
The original gotek have 6 nfet transistor that you remove .

Hi. Which jumper should I close to program the stm32?

sundbyk Reply

Jumper P6 need to be closed to get STM32 into bootloader for programming via serial.
