## Powering up the board

MR-CANHUBK344 should be powered through connector P27, or alternatively through header P28. P27 is a 5-pin JST-GH connector. Pin 1 has been indicated by the yellow triangle in the picture below. A voltage between +5 and +40V should be applied to pins 1-2, while pins 4-5 are GND. Pin 3 is not connected. The polarity of header P28 is also indicated below.
