This board is an Arduino compatible development board for ATtiny13, ATtiny25, ATtiny45 or ATtiny85. It has all the bells and whistles you need from a board like this, and still, it measures only 42x42mm!
I made this board because I couldn't find an ATtiny DIP-8 development board that had the features I was looking for.
If you want to use the ATtiny13 with Arduino IDE, you'll have to install MicroCore.
If you want to use the ATtiny25, 45, or 85 I highly recommend installing ATTinyCore, which is by far the best and most feature-rich Arduino core for these chips. If you're using the ATiny85 you can also utilize the Optiboot bootloader, and upload code to it using the on-board USB to serial adapter.
If you don't want to rely on the bootloader for uploading programs, you'll also need an ISP programmer to upload firmware to it. the USBasp or USBtinyISP programmers are recommended, but others will work too.
The board ships with the excellent Urboot bootloader installed. It's fast, reliable, and immune to bricking itself. It occupies 256 bytes, which leaves 768 bytes for the user application. This is how to configure Arduino IDE to upload programs using the bootloader:
