Introduction

The board is simply used as an interface to a single seven-segment display.

It's designed for a common-anode display, with 57mm digit height (70mm total height).

Please note that this board is not supplied with a display.

Please note that the chainable displays have a ~4mm gap between them when connected.

There are two ways to use the board:

Simple Breakout

This just breaks out each pin on the display to a terminal block. Current-limiting resistors can be soldered onto the board for each segment, or they can be jumped with zero-ohm links if the current limiting is done somewhere else.

Chainable Display

This board has a TPIC6595 shift register on that drives the display. The board has power and data connections so that displays can be linked together to form a multi-digit display.

Because the large segment often require high voltages to light the LEDs, each board has a 5V regulator on to power the shift register.

Current Limiting Resistors

If you want current-limiting resistors fitting to the board, please specify when ordering. I will contact you to work out the value of resistor you require for your displays.
