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.

Beside the kit from our shop you need

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

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:

Solder the crystal sockets:

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

Solder the ic-socekts.

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

Solder the buzzer.

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

Solder the LEDs, take care about the polarity.

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

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.

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

You can find the indent on the marking print

Solder the USB-B-connector.

First solder the housing-tabs, than the 4 connectors

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

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

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):

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"
