JC H-bridge connection
This connector is for use with an H-bridge module. For a
single bridge module, pins 1 and 2 are the direction and
enable signals for the bridge. Pins 3 and 4 are for encoder
feedback. For a dual bridge module, pins 1 and 2 are the
direction and enable signals for bridge 1, and pins 3 and 4
are direction and enable for bridge 2.

J1 SPI interface and in-system-programming
When the shorting block on JP1 is in the SS position, J1 is
used for the SPI port. When the shorting block on JP1 is in
the RST position, J1 is used for in-system-programming.
