Chapter 1. Overview
1.1 Overview
Thanks for using 3216 bicolor LED dot matrix info board series by Sure Electronics.
Integrating four HT1632Cs as driver chips on each info board, these info boards support
16-level PWM brightness control and all LED dot matrixes displayed are mapped to the
RAM of HT1632Cs. Peripheral circuits are required to light up LEDs via the ports on the
boards, providing red, green and even yellow display when red and green LEDs are
illuminated simultaneously. These info boards can be used to display digits, letters and
even graphs. It is recommended to connect up to 2 boards of the same kind in series for
wider applications such as info display in banks, stores, households and so on. You may
refer to the following table for members of this series.
TABLE 1-1 3216 BICOLOR LED DOT MATRIX DISPLAY INFO BOARD SERIES
Product Number Product Name
DE-DP14112 3216 Bicolor LED 3mm Dot Matrix Display Information Board
DE-DP14211 3216 Bicolor LED 5mm Dot Matrix Display Information Board
Note: 4 info boards connected in series are available when the boards are powered by
5V, 2A supply. If the power supply you used can output more power and the info boards
are only used to display common ASCII, more boards can be connected in series.
However, we assume no liability for any damage or risk caused by this.

Overview
1.2 Quick Start
A 16-p in IDC cable and two pow er cords are provided for free. DE-DD210 by Sure
Electronics is used in this manual as a driver board. Program this driver board to control
the display on the info board.
FIGURE 1-5 ACCESSARIES
Note:
1. Other driver board can be used. You may refer to
2.2 Port Definition to do relative
adjustments.
2. Sample codes are provided in this manual for reference.
1.2.1 Connection of One Info Board and The Driver Board
Connect BR1 of the info board and BR1 of the driver board with a 16-pin IDC cable.

Program codes to the chip of the driver board and repower the board.
Note: If you’re not familiar with programming, try using the sample codes first.
1.2.2 Connection of Many Info Boards
First, auxiliary power cords are recommended to be used when more info boards
connected in series. Connect +5V, GND of terminal J2 on one info board and the
corresponding +5V, GND of terminal J1 on the next info board with auxiliary power cords.
The auxiliary supply should be able to output DC5V 4A. Up to two info boards are
recommended to be connected in series.
Connect BR1 of the driver board and BR1 of the info board with a 16-pin IDC cable.
Then, as shown in figure 1-7, connect two 3216 info boards and the driver board with
two16-pin IDC cables and power cords.
