RT PCA9555 headers soldered

A PCA9555 gpio addon board.

This board has Qwiic/Stemma QT connectors as well as headers available for the I2C connection.

The board is supplied with headers for the input/output connections, I2C address selection and power connector

What you will receive is:
1 x RT_PCA9555 pcb with input/output headers, I2C address headers and power connector soldered in place.

1x 50mm (2in) Qwiic cable

If you need the board without the headers and power terminal in place then see this

This also shows a screw terminal but this can be replaced by a pluggable header.

These boards are soldered as required on order.

Please advise if you want screw terminal or pluggable header in the "Special Instructions or Order Comments" at checkout.

NOTE: If you are using more than one of these boards with DCC-EX you need to add I2C pullup resistors somewhere in your I2C connection.  This is best placed closest to the command station.  If you are using a multiplexor it probably has pullups so nothing needs to be added.
