Assembly hints

1. Assembly (Skipping this can lead to troubles ! )

Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.

1.1 Make sure you have the right tools:

• A good quality soldering iron (25-40W) with a small tip.

• Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will

protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.

• Thin raisin-core solder. Do not use any flux or grease.

• A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they

cannot fly towards the eyes.

• Needle nose pliers, for bending leads, or to hold components in place.

• Small blade and Phillips screwdrivers. A basic range is fine.

For some projects, a basic multi-meter is required, or might be handy

1.2 Assembly Hints :

⇒Make sure the skill level matches your experience, to avoid disappointments.

⇒Follow the instructions carefully. Read and understand the entire step before you perform each operation.

⇒Perform the assembly in the correct order as stated in this manual

⇒Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.

⇒Values on the circuit diagram are subject to changes.

⇒Values in this assembly guide are correct*

⇒Use the check-boxes to mark your progress.

⇒Please read the included information on safety and customer service

* Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet.

1.3 Soldering Hints :

1- Mount the component against the PCB surface and carefully solder the leads

2- Make sure the solder joints are cone-shaped and shiny

3- Trim excess leads as close as possible to the solder joint

REMOVE THEM FROM THE TAPE ONE AT A TIME !

Assembly hints

DO NOT BLINDLY FOLLOW THE ORDER OF THE

COMPONENTS ONTO THE TAPE. ALWAYS CHECK

THEIR VALUE ON THE PARTS LIST!

Important

Thanks a lot for buying this MP3 player project.

For your convenience, the MP3 decoder circuit is pre assembled on a plug-in board. This kit allows you to create

a full customized MP3 player, build completely to you wishes.

Standard only infrared receiver is included to work with our K8049 but an optional RF receiver can be mounted,

for use with our transmitters VM118R - K8058 or remotes VM160T or VM160DT (DeskTop version).

The board can be used vertically or horizontally. For vertical mount , a sub board for the SD card holder is

provided. There can be mounted several types of buttons (standard all small vertical types), optionally

horizontal types can be used, or types with a longer actuator. The optional LCD uses a standard 4 bit nibble

mode, so most 2 line 16 character LCD modules can be used.

Download the user manual on our web site (check the K8095 product page)

IMPORTANT!

CAUTION:

This preassembled board contains an expensive MP3 decoder chip.

This board has been fully tested before shipping.

Treat this board with caution and mind static electricity.

Always touch an earthed metal part before handling this board.

This board contains the connector for an optional LCD, the connector must be

broken off.

The board has a V-cut slot; carefully break off this part from the MP3 decoder

board along the slot.
