This is a project board for use with an ATtiny85 (or '13, '25 or '45) . This provides an outline for the ATtiny85 in either SOIC-8 or DIP-8. Each outline has its own 1206 bypass cap. It also provides holes for an ISP header, and pads for SOT-223 regulator and associated caps on the power supply (1206 or 1210), and a barrel jack. The rest of the board is dedicated to prototyping area, providing pads for an a variety of surface mount parts in addition to some traditional DIP prototyping space.
I have always found solderless breadboard to be the most effective tool for prototyping and one-off projects - however, they all suffered from two problems. First, most of the best parts now are in surface mount packages, difficult to use with through-hole proto-board. By effectively putting SMD breakout boards onto the project board, these parts can be used as easily as through-hole parts. Secondly, the quality of the available protoboard was just plain lousy. These boards are manufactured to the standards of real PCBs, with copper on both sides and plated through holes.
In the above picture, you can see an example of what a finished project using this project board might look like. Note that this is a prototype board - the ones shipping now are as shown in the main picture.
That board is connected to a 433mhz RF receiver (just off the side of the frame), LDR light sensor and a touch switch (the three-pin connector). One of the MOSFET channels is used to drive a pair of 10v 3W LED panels off the 12V input (using that large power resistor as ballast), controlled by the touch switch - this is used for under-shelf lighting. Meanwhile, an AOZ1282 buck converter generates 4.5v to power a red power LED (rated 5W, but run well below that); when a signal indicating that I've closed the door to my room is received over RF, and the room is dark, it turns on the red light so I can see my way back to bed.

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.
