You can find such programmers in my [projects](https://github.com/wagiminator/AVR-Programmer) or you can use an [Arduino Uno as a UPDI programmer](https://github.com/SpenceKonde/megaTinyCore/blob/master/MakeUPDIProgrammer.md). - Go to "Tools" -> "Burn Bootloader" - Now you can upload your sketch # References, Links and Notes - Getting started with the new ATtiny chips: http://www.technoblogy.com/show?2OCH - megaTinyCore: https://github.com/SpenceKonde/megaTinyCore - UPDI Programmer based on ATmega: https://easyeda.com/wagiminator/y-updi-programmer - Mini UPDI Programmer based on ATtiny1604: https://easyeda.com/wagiminator/attiny1604-updi-programmer - Development board for ATtiny x16/x06 series: https://easyeda.com/wagiminator/y-attiny3216-development-board-smd ![ATtiny814_DevBoard_pic2.jpg](//image.easyeda.com/pullimage/3RoHcPujymMUzfRIByevJsvc9HSEXl7i2LM7iOrd.jpeg) # License ![license.png](https://i.creativecommons.org/l/by-sa/3.0/88x31.png) This work is licensed under Creative Commons Attribution-ShareAlike 3.0 Unported License.
