• 2 x CAN
• 2 x UART
• 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
• HSE 8Mhz for USB
• Event-loop LED
• USB to I2C adapter
• VBUS sense; 100K/100K divider

Cheapest would be:

• STM32G0B1CBU6; UFQFPN48; 128 Kbytes flash; 2048 erase page
• USBLC6-2SC6
• USB 22 Ohm in reihe
• CC1/CC2 5K1 Ohm gegen GND

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
• 3V power output to supply test ICs

Other usefull function?

• CANIO as super big; RGB-LED controller
• PEAK Klon / USB-CAN Adapter
• 1,8V; Transceiver benoetigen 2V signale
