I followed the guides but it doesn't work. I have a raspberry pi 3a using fluid connected to ender 3 and pis. Why is my serial usb-1a86 while yalls is rp2040?

Klipper is saying: mcu 'PIS': Unable to connect

V2. To use this config, during "make menuconfig" select the

STM32F103 with a "28KiB bootloader" and serial (on USART1 PA10/PA9)

communication.

If you prefer a direct serial connection, in "make menuconfig"

select "Enable extra low-level configuration options" and select

serial (on USART3 PB11/PB10), which is broken out on the 10 pin IDC

cable used for the LCD module as follows:

3: Tx, 4: Rx, 9: GND, 10: VCC

Flash this firmware by copying "out/klipper.bin" to a SD card and

turning on the printer with the card inserted. The firmware

filename must end in ".bin" and must not match the last filename

that was flashed.

See docs/Config_Reference.md for a description of parameters.
