Sander van de BorSMD components are getting more popular. They are easy to assemble in production and they get small, very small! Unfortunately with the rise of SMD the through hole version, the Dual In-line Package (DIP), is no longer available for newer micro-controllers and break-out boards are needed to use these on the breadboard.
The ATtiny1616 is available in two packages, the 20-Pin SOIC and the 20-Pin VQFN. For the 20-Pin SOIC there are some break-out boards widely available, for example: https://www.adafruit.com/product/1206
While the SOIC works great, it is relatively large. Instead, the VQFN version is only 3x3MM and allows some additional features which can be added to a custom break-out board for the ATtiny1616.
Since this micro-controller has a build in 20MHz oscillator and will run between 1.8V to 5.5V, there is no need for almost any additional components. A bypass capacitor is recommended between GND and VCC for the microelectronic and a 4.7K Ohm resistor from the programmer to the UPDI pin. The actual pin out position will match the SOIC and see here the results:
Schematic is available in the files section of this project.
Next step is preparing the Arduino IDE to compile sketches.

@Sander van de Bor not making any progress with @Simon Merrett files. All there seems to be is a pdf with a schematic, I was hoping to buy a populated breakout board. Fair point on the drazzy core, I'll get one there
Are you sure? yes | no
Ah, I see. I think @Sander van de Bor and I thought you wanted design files so that you can make some boards and then populate them yourself (because you said " try making some boards" it wasn't clear that you wanted them prepopulated as it doesn't seem like there would be much making of the boards left to do if they were populated). DrAzzy is definitely a good place to get already finished boards. Have fun!
Are you sure? yes | no
Simon, thanks for your responses. I am not totally confident of my ability to get code into an Attiny yet, nor soldering a vqfn. Therefore I was probably not clear in the first instance and confusing things further by juggling my options
Are you sure? yes | no
@Adrian Galindo do you have any experience with microcontrollers or the Arduino ecosystem? DrAzzy sells programmers too, so with one of those and his microcontroller boards you should be on your way.
Are you sure? yes | no
Sander thanks for posting this, but where is the 'files section' ? I was going to try making some boards
Are you sure? yes | no

Scroll down the page and you should see the files section.

Did the schematic that @Simon Merrett mentioned earlier work for you? I created some simple break-out boards with the ATtiny1616 using the VQFN foot print, and I do not recommend that for a try ;). There are some board available on Tindie as well and if you want to support the creator of the Arduino core I recommend getting your board here: https://www.tindie.com/stores/drazzy/items/
