Thanks for your answers. I'll check the RP1 document.On Pi5/CM5 Bluetooth has its own UART.1. Can I use UART0 without disabling bluetooth? Is CM5 UART0 shared with bluetooth? According to the answers I need to use a USB to UART bridge.EMMC/uSD is connected to higher GPIOs not present on the 40-pin header. GPIO22-27 are free for other use.2. Can I use GPIO22-27 (SDIO0 Pins) as a general purpose IO on lite/normal (with emmc) CM5 or are these SDIO0 pins (GPIO22-27) only available on normal models (with emmc)?Better check for I2C address conflicts beforehand. Othwerwise Pi5/CM5 have plenty of I2C and UART units, which are only waiting to be enabled in config.txt. Read the RP1-peripherials document.3. I think I can use SDA0-SCL0 as a general purpose I2C next to MIPI0. I also use MIPI0 interface for LCD in my hardware.
