The EZP2023 is more finicky.
. The EZP2023 is a more "premium" consumer device designed for efficiency, while the CH341A is a bare-bones, low-cost utility tool that has become an industry staple. Core Comparison Primary Advantage Extremely low cost & massive community guides. Superior speed & automatic chip detection. Speed (USB 2.0) Standard (slow for large chips). High-speed (e.g., 3s read / 9s write for EN25T80). Voltage Support Often lacks proper 3.3V/1.8V switching (requires mods). Automatic voltage selection (5V, 3.3V, 1.8V). Chip Support Mainly 24 and 25 series chips. 24, 25, 93, and 95 series chips. Form Factor Bare PCB (exposed board). Enclosed plastic housing (more durable).
