To operate an additional SD Card Reader we need to use hardware SPI interface, Raspi has two. SPI0 uses pins 19,21,23 for MISO/MOSI/SCLK, which is unusable for us as we have a Lidar on UART4, which is also using pin 21... SPI1 is hard wired to pins 35, 38, 40 for MISO/MOSI/SCLK, which cant be changed. <br />
<br />
Right now I am trying to find out a pin layout where I have no collisions. The problem is we have to use I2C, 4 different UARTs, SPI and X728 at the same time + MIPI touchscreen... <br />
