Retired: This product has been replaced by the MPTH (Message Pump Through Hole) Kit or Assembled. This page is for your reference only.

The Message Pump is a device that allows you to connect a LCD display directly to your computer. It uses a PIC micro-controller, to drive the LCD and a FTDI USB to serial chip to connect to your computer.

The Message Pump works directly with most Hitachi compatible LCD displays. It features both a straight 1x16 pin connector for newer LCDs and the older 2x7 pin connector so that you can use it with either our large 2x40 character LCD display (PN: SPL-003001) or one of your own.

Detailed usage instructions can be found here.
