The following tables show the signal name (direction) for each connector pin.
Hardware
NOTE:N/C indicates no connection and PULLUP indicates a 1k ohm pullup resistor to Vcc.
Outputs are driven by the board and received by a peripheral. Inputs are driven by a
peripheral and received by the board.
COM1 is configured as a DTE port, and is generally used to communicate with a peripheral
device. COM2 is configured as a DCE port, generally being used to connect the µFlashTCP-EP
to another computer.
Pin one has a square PCB pad and the others are round. This should be visible on the bottom of
the PCB. Pin one will also be identified on the board silkscreen with a ‘1’ and/or a dot. Dual
row headers have ODD numbered pins on one side and EVEN numbered pins on the other. The
dual row header numbering scheme follows the numbering for an IDC style ribbon cable. This
numbering may not be identical to connectors with discrete wires. Use caution when connecting
cables to the µFlashTCP-EP.
