These simple boards bring all the I/O pins of the XMegaA4s out to your breadboard.
Decoupling caps, a reset pullup and a PDI header are on all models.

There are two variants of the XMega PDI board:

Original BreadMate XMega PDI
This is the simplest variant. It's essentially an XMega32A4, decoupling caps and a PDI header. It's very easy to use and can be comfortably powered by (for example) a couple of AA batteries.

USB BreadMate XMega PDI
This variant has the same features as the original, plus:

USB powered by a 3.3v LDO regulator
USB ESD protection
Uses the XMega32A4U microcontroller
D6 and D7 wired to the USB connector (by default)
Uses a standard USB-Micro connector

Advantages

We think that these boards beat using generic TQFP adapters for the following reasons:

The TQFP chip is already soldered for you!
The chip's ground and power pins are routed and decoupled on-board
The PDI header makes it ready-to-go
It's in a DIL format.
The XMegaA4 ports are clearly labelled.

Documentation

Included

PCB with all surface-mounted components soldered on.
2 x 18-way header pins (not soldered)
2x3 Header pins for PDI (not soldered)

You will need to supply the following:

A PDI capable programmer (AVRISPMk2, USBTiny mkii etc.)
Breadboard
(Original variant) power supply (3.6v or less!)
(USB variant) USB-micro cable
Soldering equipment to attach the header pins

Getting started

Solder the header pins on. Plug into your breadboard. Apply power (either via USB or the ground/Vcc pins). Connect your programmer. Go!

Technical stuff

Pads for a crystal and load caps (0603) are onboard (original: HC49/US, USB: 3.5x2.5mm 4-pad)
SJ1 (default: connected) connects Vcc to AVcc.
(USB Variant) SJ2 (default: connected) connects USB 5v to the voltage regulator.
(USB Variant) SJ3+4 allow D6/D7 pins to be connected to either the USB connector or the breadboard pins

Remember that XMegas are lower voltage than their predecessors! 3.6v maximum Vcc.
