!> SparkFun PocketAVR and USBtinyISP **DO NOT support** AVR chips with more than 64 KiB of flash (e.g., the AT90USB128 series). This limitation is mentioned on the [shop page for SparkFun PocketAVR](https://www.sparkfun.com/products/9825) and in the [FAQ for USBtinyISP](https://learn.adafruit.com/usbtinyisp/f-a-q#faq-2270879). If you try to use one of these programmers with AT90USB128 chips, you will get verification errors from `avrdude`, and the bootloader won't be flashed properly (e.g., see the [issue #3286](https://github.com/qmk/qmk_firmware/issues/3286)).
