Decent Breakout Board

The board breaks out all of the pins; exactly what would be expected. The only issue that I had was that the JTAG port is close enough to the processor that it had some slight mechanical interference with the JTAG adapter. I took some sandpaper to the JTAG adapter's connector and now there is no interference.

Easy to assemble and works well.

I got both the ATtiny 84 and the ATtiny85 development boards. Both work well. They were easy to assemble. However, if your eyes are on the older side, then you may want to get the assembled version (if available). By their nature, you are soldering some small components.

After identifying the pins on the SPI connector and connecting a ISP device (USBASP or Arduino as ISP), one can easily burn a "boot" loader or application sketch. I found with the raw devices that one has to "burn" a boot loader to ensure the Arduino ISP timing functions work properly. The Arduino IDE "burns" a generic boot loader to the raw ATtiny84 (or 85). The Arduino IDE generic boot loader does not support programming by a serial or USB connection. But, it does work. With the generic boot loader, one needs to use a SPI connection. The raw devices have this SPI functionality built in.

The documentation does cover assembling the board. It needs to have diagram showing the SPI pin locations. This is not a major problem, if one has Volt Ohm meter to to determine the pins.

I am happy that I got these boards. They work well and come quickly in the mail

Very Good

Only tip: Solder the IC holder before soldering the pin headers. I learnt that the hard way. :) Nice product

Great Board

If it were big enough to make the crystal an option. Many people use the Tiny's with the internal oscillator. This board makes the oscillator mandatory. This ties up two pins that might be otherwise be I/O and for my use relegates it to a programmer board for programming devices and recovering others that were programmed for a crystal oscillator. Not one of my favorite 84 breakout boards.

Thanks for the feedback. Based on your input I went ahead and launched Tindie fundraisers for no-crystal versions of this board https://www.tindie.com/products/bot_thoughts/attiny244484-breakout-board-no-crystal/ --Michael
