The location of the RESET button can be used as a reference for the pin numbering when the connector is
attached to the Bolt Serial. Pin 1 will be the pin closest to the RESET button.
NOTE
The Ethernet interface is intended for configuration purposes only. Bolt Serial is not designed for
permanent Ethernet communication.
NOTE
A and B marking differs between different devices, in this product A is TX-/RX- or D- and B is TX+/RX+
or D+.
