Converting Internal MacBook Trackpad to External USB Trackpad

Hi, has anyone managed to do this? I’d like to try myself

I got a macbook but forgot the password how can i fix

"I got a hold on the new style of trackpad (started in 2016, I think) and the board schematic for a matching macbook pro. It looks like they moved to SPI for the trackpads, so I think you’d need to add another controller to convert it and at that point I don’t think you get the driver support.

Here’s some info for anyone that wants to pick up from here.

Interesting chips on the trackpad:

BCM5976C1 - There’s 2 and I think this is the digitizer and I think it’s i2cSTM32F103C8I6 - Arm Cortex-m3, capable of USB but IO is software controlled I think

Here’s the pin out for the trackpad connector on the logic board (I think you can ignore the KBD stuff since the keyboard uses a different connector):

SMC_LIDSMBUS_SMC_3_SCLSMC_PME_S4_WAKE_LSMBUS_SMC_3_SDASMC_ACTUATOR_DISABLE_LKBD_INT_LTPAD_SPI_INT_L_CONNKBD_I2C_SDAGNDGNDTPAD_SPI_MOSIKBD_I2C_SCLTPAD_SPI_CS_L_CONNKBD_BLC_XBLANKTPAD_SPI_MISOKBD_BLC_XBLANKTPAD_SPI_MISOKBD_BLC_GSSOUTTPAD_SPI_CLK_CONNKBD_BLC_GSSCKPP5V_S4_TPAD_CONNKBD_BLC_GSLATSMC_VIBE_L

then everything else is power or ground (5v, 3v, 0v - active gnd, 12.6v on a fuse)"

"Hi guys,

I also looked for info about this mod

I would like to do this on the touchpad and keyboard of a 2011 macbook pro 17.

Were you able to do it?"
