Plain-language definitions for the technical terms used above.

AVR

AVR is a family of 8-bit microcontrollers (made by Microchip, formerly Atmel) used in many classic Arduino-style boards such as the Uno and Nano. They are widely supported but older, which can be a limit for memory- or speed-intensive tasks.

ISP

In electronics, ISP usually means In-System Programming, a way to load firmware onto a microcontroller while it stays on the board (often via an ICSP header), or an Image Signal Processor, hardware that turns raw camera sensor data into usable images and offloads the main CPU. The surrounding context shows which meaning applies.
