This development board around a 68HCS08DZ60 microcontroller from Freescale aims initially to be a platform for experimenting with the CAN bus. So it’s equipped with a CAN driver and the bus is available on a 3-way connector. The board also carries an RS-232 driver. Hence the microcontroller’s SCI1 port is available on a standard 9-pin female D connector. The CAN driver and the RS-232 driver can be disconnected from the microcontroller via jumpers.
