Assembly-instructions for the aTeVaL-Board

To get a bigger image, just klick on it.

The assembly takes about 30 minutes for a practiced hand.

Needed material

Beside the kit from our shop you need

  • a soldering iron
  • tin solder
  • pliers (for cutting of the wires)

Solderjumper

Depending on your needs you have to set different solder-jumpers.

Version 1.2

Solderjumpers for PCB-version 1.2 can be found here

Version <1.2

For getting feedback at the programming-progress you have to solder the solderjumper at the red LED on the programmer part:

To use the LEDs and the buzzer, you have to solder the solderjumpers on the bottom side of the pcb:

Crystal-socekts

Solder the crystal sockets:

Testhardware

Solder the switches and the two potentiometers. (since hardware-version 1.1: the reset-button is salmon)

IC-sockets

Solder the ic-socekts.

Be very careful and watch out, that EVERY pin is beneath it's hole and not beside it!

Buzzer

Solder the buzzer.

Take care about the polarity, it's marked at the sticker and on the housing.

LEDs

Solder the LEDs, take care about the polarity.

The flat side of the LED is also marked on the pcb.

Header

PCB-version 1.1:
Cut off the header for the jumper: 
1-row header: 2x 2-Pins, 3x 3-Pins
2-row header: 2x 2-Pins, 1x 4-Pins
PCB-version 1.2:
Cut off the header for the jumper: 
1-row header: 1x 2-Pins, 4x 3-Pins
2-row header: 2x 2-Pins, 1x 4-Pins

Solder them after cutting them.

The easiest way is to solder one header after another. Be careful about their direction, headers want to get soldered in any direct but not straight.

Header-socket

Solder the header-sockets, take care about the orientation.

You can find the indent on the marking print

USB-B-connector

Solder the USB-B-connector.

First solder the housing-tabs, than the 4 connectors

Capacitors

Solder the capacitors, again, take care about the polarity.

The negative pole is marked with a white line on the housing

Crystals

You get 3 different crystals with the kit. Every AVR is running with it's internal RC-oscillator, therefore, the crystal is optional and has to be activated in the fuses.

Cut the pins that there are about 5mm left:

Put the crystal in the socket (optional):

Jumper

Plug the jumper on the header: 

PCB-version 1.2: V1.2 has a 3-pin Powerjumper.
For power over USB: plug jumper at "5V"
For power over the optional LDO (bottom side): plug at "LDO"
