MAX3421E breakout boards
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.
Populated PIC-80 breakouts
A year ago, I needed to prototype a design which used PIC18F8722. It’s a nice microcontroller with plenty of ROM, RAM, and peripherals. It comes in 80 pin 0.5mm pitch TQFP package. To use it in prototyping, I designed breakout board which holds the micro, crystal, and filter and decupling capacitors. With time, I changed the layout to accommodate other PICs in the same package and recently made a variant which takes any 80-pin PIC in TQFP-80 package in production, at the time of this writing. This includes:
- older PIC18Fs
- newer J-series PIC18s
- “Classic” dsPIC30
- J-series dsPICs
- PIC24s
