The EZP2023 uses a faster microcontroller and allows you to toggle clock speeds via software (usually 6 MHz, 12 MHz, or 24 MHz).
The EZP2023 is a dedicated SPI programmer housed in a sleek, aluminum enclosure. It uses a high-speed USB interface and is designed specifically for 24 and 25 series memory chips. It typically retails for slightly more than the CH341A but still falls firmly in the "budget" tool category. ezp2023 vs ch341a
