• 2xCAN
• 2xUART
• Connect DAC to ADC.
• 2 further ADC inputs with different resistor dividers.
• Can even test debouncing; PWM to GPIO Input
• Test slope counter, Hz etc.
• Program internal flash
• Verify CRC calculation
• Any present SPI flash
• Any present I2C flash
• Compare systimer with RTC
• Test some patterns in UID
• UCPD test platform
• ADC fuer USBCPD

Cheapest would be:

• STM32G0B1CBU6; UFQFPN48; 128 Kbytes flash; 2048 erase page

Connections:

• Debug
• USB-C; FRSTX, CC1, CC2 (Fast Role Swap Transmit)
• PWM-LED + 5V output like CANIO
• I2C like CANIO
• CAN-Bus x 2, via solder-bridges
