不是堆功能！正点原子DM40C内部电路拆解，设计逻辑一次讲清

Deep dive into the ALIENTEK DM40C! We’re skipping the specs and going straight to the core: The Engineering Logic. 🔧 In this episode, we perform a comprehensive internal teardown of the ALIENTEK DM40C 3-in-1 tool. Rather than focusing on "premium components," we analyze the design philosophy from an engineer's perspective: Power Architecture: How the battery supply system is optimized for a handheld device. Measurement System: The logic behind the multimeter module. Oscilloscope & Signal Gen: Balancing signal integrity with portability. Design Trade-offs: Which modules took priority and why? If you value Circuit Design Logic over just another spec sheet, this hardware analysis is for you. "Measurement is for understanding, but tearing down is for the truth!" 🚀
