We're going to begin beta testing the MK66FX1M0 chip for a high-end Teensy.
Update: See post #8 for latest status. (special thanks to defragster for keeping #8 updated)
The following people will receive free beta test boards. PJRC will pay for shipping too. For packages outside the USA, you'll need to pay any extra tariff/fee the carrier charges upon delivery.

Unfortunately, we can't ship everyone a board right away, so they'll be made in 3 or maybe 4 rounds. Rounds 1 and 2 will be a large (approx 3x3 inch) board with the TQFP version of the chip, with sockets at the intended final form factor (2.4 by 0.7 inch). Round 1 will have 10 boards, shipping next week. Round 2 will add 18 more boards over the next few weeks. Round 3 will be a pre-production run of the actual board with the BGA version of the chip and final power supply circuitry. If we can't make enough on these first 3 rounds, a 4th round might be added.
Everyone on this list has been a regular forum contributor or software developer. Robin and I really appreciate everything you've done. We want to get all of you boards as early as possible. But as a practical limit with so much hand soldering, we need to prioritize. So far, for round 1 we will send to:
Frank B, Theremingenieur, KurtE, dgarcia42, manitou, Defragster, sumotoy, el_supremo
If you'd like to receive a board in round 1 or 2, the magic words are "I do have time for beta testing" and some idea of what things you might try testing. If you're busy, I recommend waiting for round 3, which will have a nice USB host current limit circuit that's not present in rounds 1 & 2. If there are extra boards, we might open up a 4th round and perhaps include people not on the original list.
To receive a beta test board please contact Robin directly at robin at pjrc dot com, especially if your forum email address is not your primary one.
I'd like to ask everyone to please avoid posting photos of the boards, and to keep all conversation on this forum thread. I'm trying to allow openness and access to technical information while avoiding premature promotion & vaporware. Hopefully a text-only forum thread is a good compromise. Please don't post pictures, especially on social networks, until we've finalized a page on the website (with photos) for ordering the final board.
