Great quality board, great for breadboarding. I ordered 2 ... i should have ordered more. There is some good info on the site how to program it with avrdude / usbasp and some basic tutorials. Really fast delivery within 1 week i had the boards delivered.
A must have if you want to experiment with the 841.
I really like the setup of the tutorials on the website, plenty of eye-openers for me, because when reading the ASF-documentation from ATMEL confusion takes posession of my brain. Very well structured information, but at the moment of coming up to speed with learning at the 4th chapter, the tutorials end. I am looking forward to the 5th and later chapters!
The hardware is well built, intuitive how the headers to be placed. Muchos gracias from Czech Republic.
What a great little board. I've designed several 841 based boards for use in various applications and this little breakout board proved invaluable in simplifying the software development for them. Simply solder on the header pins, plug the breakout board into a breadboard and its ready to power and program. I mounted the two side headers pointing downward and the ICSP header pointing upward so its ready to plug and play. A definite must for anyone planning on using ATtiny841 based projects.
This is a breakout -- which is different than a full "arduino ready" boards usually are.. very bare bones. Board looks well done & soldering is good. Chip fires up, so all looks good. For the price, you should buy a few! -- Update Jan 2016 -- I ordered 2 more of these & they arrived very quickly. Perfect little boards. I used to love the attiny85, but this is better at about the same cost.
The LED modules arrived well packed downunder in just 15 days. I only needed to solder the pins for plugging into a breadboard - the resistors and LEDs were already expertly soldered in place. Hint: when soldering the pins, plug them into a breadboard, place the PCB over the top, solder one corner, make sure it's nice and flat, solder the rest. A quality item. Perfect!
