About
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.
Prototyping Board:
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.
Other boards:
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.
Shipping Policies
We ship within 1-3 days of receiving an order (usually closer to 1 day).
Please be sure that the address given to Tindie is accurate, and includes your street name and number - company name is only required if shipping to a commercial address. International orders require a valid phone number.
Domestic packages that go more than 1 week without a tracking update will be presumed lost in the mail and refunded or reshipped as buyer prefers. Any international packages can be delayed in customs without warning for 2 weeks or more. After 1 month without a tracking event, we will reship or refund a missing order (as you prefer).
We do not open inquiries through the postal service - experience has shown this to be futile.

Response from Azzy's Electronics | Feb. 7, 2019
That's a good suggestion - I hadn't thought of writing up a guide to migrating to ATTinyCore from other cores, and to ATTiny841 from ATTiny84.
The main differences are:
ATTiny841 has two hardware serial ports, named Serial and Serial1; they can be used like the serial ports on any other AVR through ATTinyCore. The ATTiny84 has none (though if using my core there is a builtin software serial implementation that uses the ACO vector, so it can be used without interfering with use of PCINTs for other purposes like the SoftwareSerial library would - see the ATTinyCore documentation for details - probably not relevant to you).
ATTiny841 has an additional 16-bit timer, timer2, which is identical to timer1. The PWM pin assignments are also more flexible - you can move the PWM outputs around between pins; this can allow some behavior that could never be achieved on most AVRs (unfortunately the coolest thing I did with this is covered by an NDA, so I can't go into further detail)
The ATTiny841 has a hardware SPI, and hardware I2C slave interface, while the ATTiny84 has a USI.
If using the Arduino IDE with ATTinyCore, you can use unmodified libraries designed for SPI or I2C devices, and the version of Wire and SPI libraries included with ATTinyCore for the 84 or 841 (these versions of the library automatically use the correct implementation of I2C or SPI for the hardware, and provide a compatible interface, so no changes to the library are needed). With the Arduino IDE and other cores that support the ATTiny84, you needed to use a different library for SPI/I2C that used the USI, and modify the library for the SPI or I2C device to make use of that library instead of the standard Wire or SPI library. If you are not using the Arduino IDE, you need to handle this yourself (the most notable hardship is that I2C master requires a software implementation of I2C - ATTinyCore handles this for you in Arduino-land, but if using Atmel Studio or other tools, you'd have to do this yourself)
On the ATTiny84, the internal oscillator is pretty close to 8MHz across the whole operating voltage range (ie, close enough for serial to work), but strongly temperature dependent (particularly on the low end). On the ATTiny841, the internal oscillator is very close to 8MHz across the whole temperature range below 4v, but the speed increases rapidly as voltage increases above that - such that above ~4v, it's not close enough for serial to work if you don't account for that (typically by adjusting OSCCAL). If using a crystal, which I recommend for any application where serial functionality is used (on any processor, not just this one), this is not relevant.
I've added an issue to ATTinyCore on github regarding this; you can follow this for updates on the progress towards more formal documentation. https://github.com/SpenceKonde/ATTinyCore/issues/285

Great product !
For RN2483 breakout (bare board)
So, the product is, even if in my case, I must split the PCBs, very great, the quality is there.
Great commucation ! ( due to my delivery issue)
The product is well documented, this point must be raised , thxxxx

Exactly what I was looking for!!!
Only down side is lack of documentation (its easy enough to figure out by following the traces, but a few more labels on the board or a graphic explaining everything would save time, at least to me as I've very new to circuit design).
