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 parts in these packages effectively.
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!

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
I build projects with Arduino (ATtinies almost exclusively, never anything bigger than a '328p) and Espruino (often both working together), and I make a lot of circuit boards for these projects. Particularly after using my ATtiny-prototyping board for my own projects, I realized that these would be useful to other people, and decided to start selling them here on Tindie.
Strip Board, Protoboard, prototyping board, solderable breadboard - whatever you want to call it - it has been a mainstay in electronics prototyping for decades, and hasn't changed much in the interim (not even in production quality, as they're still often single-sided and/or manufactured from low-grade phenolic resin instead of FR4). My prototyping board creations bring these into the modern era, offering a combination of 0.1" through-hole prototyping areas (consisting of groups of 2, 3 or 4 pins connected together, like solderable breadboard) and pads for common surface mount packages connected to through-holes for easy soldering. To handle projects of all sizes, I offer prototyping board as large as 4" x 4", down to less than an inch square in my Mini Protoboard line. Unlike most commercial prototyping board, these boards are made to the same quality standards as real PCBs. Through-holes are plated, and the boards are double sided. These are offered in both generic versions, and ones tailored to specific microcontrollers, like the Tiny84/85, or microcontroller boards, like the Espruino Pico, Arduino Pro Mini, and the wildly popular ESP8266.
ATtiny breakout boards:
I love the ATtiny lineup, particularly some of the less popular ones, like the incredibly full-featured ATtiny841, ATtiny1634, and ATtiny828. Breakout boards for these that had the features I wanted were not readily available - so I made my own. I've since expanded my product line to include breakout boards for the ATtiny861, ATtiny167, and ATtiny88 - and all of these are available both as bare boards and assembled. In addition to designing the hardware I also maintain [ATtinyCore Universal](https://github.com/SpenceKonde/ATTinyCore), which enables Arduino support for all these ATtiny's and more.
I also sell a number of other boards to fill what I felt were gaps in the market, including a breakout board for the popular LoRa/LoRaWAN modules from Microchip (the RN2483 and 2903), which has become one of my top selling items. I also sell MOSFET drivers and breakout boards for logic level MOSFETs operating at logic levels of 2.5v and lower - while a great number of MOSFETs are available that operate with very low gate voltages, these are almost invariably SMD parts which are difficult to use without a properly designed breakout board.
