A breadboard-friendly DIL format board for A4 XMegas
This is our simplest XMega board. It just plugs straight into a breadboard.
All the I/O pins of the XMegaA4 are brought out to clearly labelled pins. Port pins are kept together, so if you need all the pins on a port - they're next to each other.
This board has an XMega32A4, some decoupling caps, a reset pull-up resistor, a PDI header and a CR1220 coin cell holder.
It's very easy to use - just supply power through the bread-board pins, or from a coin-cell battery (not included).
Hardware design (schematics and board) are available below.
You will need to supply the following:
Solder the header pins on. Plug into your breadboard. Supply power. Connect you programmer. Go!
We've got a page with some XMega examples, which might be useful.
Pads for a standard HC49/US crystal and load caps (PTH) are onboard
Pads for a watch-crystal are onboard.
SJ1 (default: connected) connects Vcc to AVcc.
Remember that XMegas are lower voltage than their predecessors! 3.6v maximum Vcc.
We are now using the U variants of the XMegaA4s in the Vanilla boards. These are a more recent version of the silicon and are binary compatible with the non-U variants. For more information, see Atmel's Application Note AVR1021.
Version 2.0 of the board has swapped the location of the AVcc/Vcc and Gnd/Reset pins so they match our other A4 boards.
added: CR1220 coin-cell holder
change:Rst/Gnd and AVcc/Vcc location swapped
change:PTH holes for HC49 crystal and caps
added:PTH holes for watch crystal
