+5Vdc Power Connector (J14)
The TMCP700 has a 4-pin header that can be used to p5Vdc
power to offboard devices. This power is derived from the fused +5Vdc
power on the MCP750. Any external device powered from this connector
must not draw more than 200mA. The pin assignments are listed in the
following table.
