ATTiny84/85 project boards back in stock with improved silkscreen, along with new and improved Wemos D1 Mini prototyping shields.
I've always preferred to build prototypes using "solderable breadboard" style prototyping board, which has holes tied together in groups of 3-4. I offer three different versions of this 2"x4" prototyping board, with varying amounts of SMD footprints. All of these are manufactured on high quality 1.6mm thick FR4 material with lead-free HASL surface treatment, double-sided with plated through holes. Compare to other prototyping board, which is often made on low quality single-sided phenolic resin with no surface treatment in the copper - we wouldn't use that garbage in our projects, and neither should you.
Solderless breadboard, plain, simple and well made. Not every project requires working with SMD components - and not every maker likes working with them. Whether your project simply calls for a lot of through-hole parts and passives, or you aren't equipped for soldering SMD components, this is the board for you!
This general purpose project board provides a large through-hole prototyping area, along with a small power supply section (featuring two regulators), and a small SMD prototyping area, with pads for 1 SOIC-16 (or 2 SOIC-8) part, or - on the other side) 2 5050 PLCC-6 LEDs or SOT-23-6 and one DFN-6. DFN-6 is attractive because there are a number of interesting sensors (mostly light sensors) that come in that package, many for which breakout boards are not available (or not available at reasonable prices).
Now building prototypes and one-off projects with SMD components is as easy as with through-hole parts! This general purpose hybrid project board combines groups of through-hole pins (in rows of 2 and 3, with exposed copper between them) with exposed ground and distributed Vcc traces with the most popular surface mount footprints, broken out to through-holes. Holes for a center positive power supply barrel jack are provided (or wires can be soldered onto the holes), connected to pads for a SOT-223 regulator. The Vcc trace is not committed, and could be connected to Vin, Vusb, or Vout (or anything else). Pads are provided for a mini-USB connector as well - I have found micro-usb connectors to provide insufficient durability.

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.
