RGB LCD Shield for Arduino 65K color KIT V2 Assembly Guide

The RGB LCD shield for Arduino 65K color KIT includes all the components to assemble a ready to use LCD shield for Arduino and compatible boards like Freeduino.

The LCD module has a backlight made of 2 white LEDs that requiere approximate 9V with a max 19mA current to work. As this voltage level is not available on the Arduino board, I used an ST232 RS232 driver to get 8V DC from the standard 5V Arduino power supply. The backlight driver circuit now included in the main RGB LCD shield PCB.

It contains the following components:

1 x RGB LCD module

1 x RGB LCD shield PCB

1 x LCD module to PCB soldering adapter

1 x LM317T variable voltage regulator

2 x 10uF electrolytic capacitors

5 x 0.1uF ceramic capacitors

1 x 330 ohm resistor

1 x 430 ohm resistor

5 x 1Kohm resistors

5 x 1.3Kohm (1K3) resistors

1 x 28-pin male breakable header (you need to cut 2 8-pin sections, 2 6-pin sections)

1 x ST232 RS232 driver IC

1 x 110 ohm resistor

Step 1 Mounting the Adapter Pads on LCD

The first step is to unpack the KIT.

Let’s start with the main RGB LCD shield PCB. The LCD module needs to be soldered first. Separate the LCD module and a small green thin PCB used to attach the LCD module to the main black PCB.

Apply some solder in one of the pins of the LCD module, you can choose either pin 1 or pin 10 (pin 1 is the one to the right of the picture).

Once the solder is applied, place the small thin PCB and align the 10 pads to the 10 pads on the LCD module. Heat the pin that has the solder to attach the small thin PCB (the adapter). Once you are satisfied how it is aligned (make sure the pads are correctly aligned, to avoid shorting the pins), solder the rest of the pads.
