# Stand-alone programming AVRs using CircuitPython ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/049/926/medium800/hacks_icon_t.png?1515373660) If you've ever wanted a _stand alone_ AVR programmer, that is super easy to use, you've come to the right place! This guide will show you how to turn any CircuitPython powered board with 4+ GPIO pins into an AVR progammer all on its own. **No software like avrdude is needed** , this software will program the chip all on its own, just drag the HEX file onto the CircuitPython disk drive. Perfect to putting bootloaders on empty chips, or field-reprogramming a project! # Supported Chips In theory, any and all AVR chips with SPI-programming interfaces are supported. However, we only have examples for **ATmega328P** chips (used in Arduino compatibles), **ATtiny85** (used in original Trinket/Gemma), and **ATmega2560** (Arduino Mega compatibles) To program other chips, you'll need to find out the signature, size of the flash, and the flash-page size. You can find this in the datasheet or in `avrdude.conf` Warning: - [Next Page](https://learn.adafruit.com/stand-alone-programming-avrs-using-circuitpython/wiring.md) ## Featured Products ### Circuit Playground Express [Circuit Playground Express](https://www.adafruit.com/product/3333) **Circuit Playground Express** is the next step towards a perfect introduction to electronics and programming.
