RA2L2 low-power MCUs are the industry’s first MCU to support USB-C Revision 2.4 with 15W CC detection, USB FS, CAN, I3C, and low-power UART.

After this tedious step, he designed a PCB that hosts an Arduino Nano to accept input, two MCP23017 GPIO expanders to give it enough outputs, and CD4066BE CMOS switches to trigger the connections.
