These prototyping boards have two power rails down the middle, and two rails along the outer edge, and a pair of mounting holes on either end. On either side of the power rails are holes in a typical "breadboard" pattern for easy use with parts in DIP packages, while either end has holes grouped in a pattern at right angles to the power rails - these holes are ideal for wiring connections to external devices (for example, the serial programming header on a standalone arduino). The mounting holes are on a breakaway tab, so either or both pair of mounting holes can be removed.
These are great for projects too small to justify using one of my larger prototyping boards, and are ideal for accomodating an IC in DIP package and thier supporting components - for example making standalone Arduino or ATTiny projects (though I also sell prototyping boards designed specifically for the ATTiny84 and ATTiny85), or more mundane tasks using 555's, comparators, or level shifters.
All boards are made on high quality 1.6mm FR-4 with solder mask on both sides, and HASL surface treatment - just like all our other boards. Many manufacturers of prototyping board use the brittle low quality brown phenolic PCB material, and/or leave the copper exposed, inevitably leading to corrosion and degradation in solderability over time. We wouldn't settle for such inferior prototyping board in our own projects, and you shouldn't either!
1.2" x 3.6" (DIP-40 - great for making standalone Atmega 1284p) 1.2" x 3.1" after removing mounting tabs
1" x 2.7" (DIP-28 - great for making standalone Arduino, ATTiny861 or ATTiny4313) 1" x 2.2" after removing mounting tabs
1" x 2.0" (DIP-16 - great for ATTiny84 projects or use with standalone IC's) 1" x 1.5" after removing mounting tabs
2.5 x 2.0" (2.0" x 2.0" after removing mounting tabs) Unlike the others, this is a larger 2-inch square prototyping board, with four "ears" for the mounting holes. This provides additional freedom in mounting options over the others, in addition to providing enough space for a more complicated, multi-chip circuit.

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.
