These offer a new take on breakout boards for SMD devices by breaking the pins out to groups of 2 or 3 holes each, instead of the single hole provided on typical breakout boards. This, combined with the exposed and accessible ground trace around the perimeter, allows some supporting components to be included right on the breakout board without interfering with connections to other parts of your project.
These prototyping breakout boards are available in three versions, corresponding to 20-pin, 28-pin, and 32-pin quad flat packages. QFN and VQFN packages often have an exposed pad on the underside (typically connected to ground) - for these packages, an exposed pad is provided, tied to the mounting holes and exposed trace along the perimeter. While QFN and VQFN are never fun to solder by hand, these quality breakout boards will help you use use parts in these packages effectively for prototypes and one-off projects, without having to make a custom PCB for your project - or being charged so much for a breakout board that you might as well made your own PCB.
TQFP-32/QFN-32 - Two-pack of boards supporting either TQFP-32 or 0.65 mm pitch QFN-32
QFN-28/VQFN-32 - Two-pack of boards supporting either QFN-28 ( 0.65mm pitch) or VQFN-28 ( 0.45mm pitch). Shown in the picture is a board with an ATtiny88-MU (QFN package) mounted along with supporting components.
QFN-20/VQFN-20 - Three-pack of boards supporting either QFN-20 ( 0.65mm pitch) or VQFN-20 ( 0.5mm pitch - aka MLF-20). Board shown in picture has ATtiny1634-MU (MLF-20 package) mounted along with supporting components including external crystal. Discounted version available: Due to a typographical error, the silkscreen on these boards incorrectly identifies them as QFN/VQFN-25. A new version of these boards with corrected silkscreen and better panelization is now available, so the old ones are available (while supplies last) at special 2-for-1 pricing!
|Shipping Rate||Ships From||First item||Additional items|
United States Postal Service: Economy (untracked, bare boards only)
The cheapest shipping option available, for bare boards within the United States only.
United States Postal Service: First Class Tracked (recommended, cheaper than economy for 5+ items)
United States Postal Service: Priority Mail - Flat rate (fastest, tracked)
Domestic shipping via USPS Priority Mail - USPS advertises 1~3 day shipping time within the continental United States. This is a flat rate for any quantity of items - shipping is via a USPS small flat rate box (unless you place a massive order that needs a larger box; I am happy to cover the added shipping fee for an order of that size!)
United States Postal Service: Priority Mail Express
The absolute fastest domestic service offered by the postal service. This is typically one day faster than Priority; but as you can see, that is a very expensive day. Orders placed via this shipping method will be given top priority in handling.
