First batch of MAX3421E arrived today, three days ahead of schedule, from PCBcart. The quality is good. It’s now for sale in my store, price $8.50.
In a week, I will be selling main Maxim parts for this board, as well as less exotic components, such as 12MHz quartz crystals and USB A connectors. If you want to get notified when it happens, send me an e-mail. In the mean time, you can try to go sample route
, Maxim is known to be generous, at least to US residents.
[Update] I now have MAX3421Es for sale, price $8.00.

I have one of your MAX3421E breakout boards but do you have a circuit diagram? I want to check its electrical connectivity.
Thank you,
John,
The Eagle files for this board are here -> http://www.circuitsathome.com/chome_downloads/MAX3421E_breakout_v10.zip . If you don’t have Eagle, I can generate a PDF of the schematic and send it to you. Let me know,
Oleg.
