Cheaper ISP Programming with a USBTiny
When I first started with Atmel Studio, I was a little taken aback at the cost of the programmers needed to flash my programs onto the microcontroller. After a fair bit of research I came across a great project – the USBTinyISP. This ticked a few boxes for me: it was open-source, it was easy to build yourself (if you prefer that), and it was cheap to buy (if you didn’t want to build one). I use my USBTiny all the time to program my Toadstool Boards.
