JFET

Direct plug-in buzzer module

Overview

I was inspired by an article on Zhihu: https://zhuanlan.zhihu.com/p/391336125 This module can use buzzers with voltages of 3.3V and 5V by replacing the resistor. The buzzer is connected in parallel with a capacitor (to reduce interference) and an IN4148 diode (to prevent the buzzer from generating a reverse spike voltage that damages the transistor), and is compatible with active and passive buzzers. The soldered bent pin header is directly inserted into the circuit board to save space.

In the process of building FSM, I encountered a problem: The PPT says that 02 selects V+, but in practice I can't select X+ with 01, but 0x80 selects X+, 0x40 is X-, 0x20 is Y+... Therefore, I feel th
