On USB-I2C/LIN-CONV-Z what is VDD voltage? 3.3V?
The USB 5V supplies the USB chip and the micro and the I2C pins have pull ups to the USB 5V. If LIN is used it must receive nominally 12V from the target. It will work with 5 to 18V.
What is the connector and pinout you should drop on your target board in order to connect this serial loader to your target? I can't seem to find a schematic or BOM on this interposer board.
