Sanguino Breakout v1.0 Complete Assembly

Build it!

These are the instructions on how to build the Sanguino Breakout as a single integrated board. If you'd like to build one as a shield for a Sanguino, follow these instructions instead.

Solder Pin Headers


The pin he

10K resistor


Solder the resistor in any orientation. It is marked brown / black / orange.

22pF capacitors


These are the tiny yellow capacitors. They can be soldered in any orientation.

Serial Headers


Solder in the right-angle headers into the end of the board as shown.

40-pin DIP Socket


Line up the DIP socket so that the dimple on one end lines up with the dimple on the silkscreen. Solder each pin in.

Red and Green LEDs


The LEDs need to be inserted in the proper orientation. The short leg of the LED goes into the flat side of the LED silkscreen.

16mhz Crystal


This is the crystal oscillator. It may be soldered in any orientation.



This is the polarity protection diode. It needs to be soldered in in the proper orientation. There is a band on the diode. Line it up with the band on the silkscreen and solder it in.

Reset Button


The button can only be inserted into the PCB in one orientation. Insert it and then solder it in.

1K Resistors


These are the resistors for the LEDs. They need to be mounted vertically, so bend one lead over and solder the resistors into the board.

100nF Ceramic Capacitors


The ceramic capacitors can be soldered in any orientation. There are 4 of them. Solder them all in.

Auto Reset Jumper Header


This is the jumper to enable/disable autoreset. Solder in a 2-pin header. It helps if its soldered in straight.

Auto Reset Jumper


Put the jumper onto the header you just soldered it on. This enables the auto-reset functionality.


If you skip this step, you'll have to press reset every time before you upload your sketch.

Power Selector


This switch allows you to choose between USB and External power. Solder it in any orientation.

JTAG Header


This is the header to access the JTAG functionality. There is a notch in the IDC header that should line up with the silkscreen.

DC Power Jack


This is the jack for power input. It will take quite a bit of solder to solder it into place, so don't be shy.

ICSP Header


This is the header to directly flash the atmega644P chip. The pins can be soldered in any direction.

100uF Electrolytic Capacitors


These capacitors need to be soldered in the proper orientation. One side is marked as negative. The other pin is positive. Insert the positive leg in the side marked positive. It should look like that pictures.



This is the power regulator. Solder it so that the metal backing tab faces outwards.

Insert atmega644P


Now is time to insert the atmega644P chip. Line the dimple up with the socket (and more importantly the silkscreen). Take care to not break / severely bend any legs as you insert it.
