This board is an addintion to the 8 Channel Quantizer. Replacing the 5 LEDs which show BANK and SCALE selection, the LCD shows the scale number, name and notes (starting with C).

The 3 PIN Power taps off the digital board power pads

Build Notes:

The BOM includes Digi-key and manufacturer part numbers for the more unusual components

The Potentiometers and the connectors for the LCD display need to be soldered to the bottom of the board.

Connect headers as shown on PCB and LCD module.

CONNECTING TO THE QUANTIZER MODULE: Power for the module should be tapped off of the power pads on the Quantizer DIGITAL BOARD. The lines to the 5 pin connector should come from the RLED points on the digital board.
