Is Goldilocks not available anymore?

An advanced Arduino-compatible board with ATmega1284P and ATmega32u2 MCUs for experienced users. More RAM than a Mega, but in a convenient Uno-style form factor. [Product page]

Is Goldilocks not available anymore?

@johnb, I noticed you said the Goldilocks is retired in you other post. I was hoping to be able to get more. Will they be available for ordering? Or do we have to wait for the next version and how soon would that be?

This is true, we don't have any more retail units available. The next unit will be the new 1284P board which we're discussing at the following page:

First, if you're using linux there is an enumeration problem between LUFA and linux. Just resetting the 32u2 doesn't achieve re-enumeration. You actually need to power cycle the interface. This doesn't seem to affect WinXP from what hiunino is reporting on another thread.

I think everyone (eg. Seeed, Sparkfun, Freetronics and me) have realised that using the ATmegaxxU2 as a USB-Serial interface is fraught with problems.
Using a FTDI solution is in every way better.

The next Goldilocks will certainly not be using a ATmegaxxU2 for the interface.

Just to clarify Freetronics' position on this: There are regrettably some problems with the unique atmega32u2 firmware installed on the Goldilocks. However we don't know of any significant problems with the 16u2 firmware that is used on almost all our other Arduino-compatible boards. It's generally reliable and 100% compatible with the Arduino reference designs. We don't have any immediate plans to stop using it.

Using an FTDI-based chip is also a valid approach, which is why Jon designed it into the ArduPhone design for the 2014 Arduino MiniConf. It's also useful if you're making a Duemilanove compatible board (like the Seeed one). However they're both workable solutions, and we're not exclusively abandoning one for the other.
