NOTE
The PowerSBC does not connect to the 5.0V_LR power rail which is
powered by 5 V linear regulator when used with the motherboard. This
rail is powering the VDDA_SD & VDDA_EQ (ADC supply) and
VRH_SD, VRH_SEQ (ADC reference voltage). When using the
daughter card standalone (without the motherboard) it is required to
connect the 5.0V_LR and the 5.0V_SR rail as mentioned in
Table 10
in
order for the microcontroller to come out of reset.
Power SBC has High Speed CAN Transceiver & LIN Transceiver. CAN bus from SBC is terminated
with DB9 connector (J508) and LIN is terminated with 4-pin Molex connector (J503) in the Daughter
Card.
The connections of the J508 (CAN) from PowerSBC are detailed in
Figure 13.

The connections of the J503 (LIN) from PowerSBC are detailed in
