The SmartLCD Keypad Kit is an optional add-on for the Hobby Components Smart LCD (HCMODU0122). When constructed this add-on board connects to the SmartLCD's keypad header using a single 4 way cable (supplied). Once connected it adds the additional features of keypad control (up, down, left, right, select, and back) and audible output to your end application.

Access to button states and speaker output is then available via the SmartLCD's I2C or UART interfaces using its built-in commands (See the SmartLCD's manual for more information)

Build Guide:

Resistors

Image


Locate the following pads on the PCB and solder the appropriate resistors in place.

R8 – Resistor Value: 10K (BROWN, BLACK, BLACK, RED, BROWN)

R7 – Resistor Value: 5.6K (GREEN, BLUE, BLACK, BROWN, BROWN)

R6 – Resistor Value: 3.6K (ORANGE, BLUE, BLACK, BROWN, BROWN)

R5 – Resistor Value: 2.2K (RED, RED, BLACK, BROWN, BROWN)

R4 – Resistor Value: 1.8K (BROWN, GRAY, BLACK, BROWN, BROWN)

R3 – Resistor Value: 10K (BROWN, BLACK, BLACK, RED, BROWN)

R2 – Resistor Value: 1K (BROWN, BLACK, BLACK, BROWN, BROWN)

R1 – Resistor Value: 100R (BROWN, BLACK, BLACK, BLACK, BROWN)



4 way R/A header pins

Image

The 4 way header can be soldered to the either the upper or lower side of the PCB depending on your preference. Soldering tip - Solder just 1 pad first then check to make sure the header is flat against the PCB. If it isn't it will be easier to adjust. Once level the remaining 3 pads can be soldered.



Speaker

Image

Solder the speaker to pad SP1. Note that the speaker should be orientated so that the '+' symbol on the speaker is on the same side as the '+' symbol on the PCB.



Transistor

Image

Solder the transistor to pad Q1. Note that the transistor should be orientated so that the flat side of it's case matches the flat side of its PCB symbol.



Switches

Image

Solder the six 12mm x 12mm push switches to pads SW1, SW2, SW3, SW4, SW5, and SW6. Note the orientation of the pins in the above diagram.



Switch caps

Finally, add the caps to the push buttons so that they match the above image.
