図の背後にある意思決定を読み解く。
01
Use a 2S Li-ion battery and 5V buck regulator to power the ESP32 and ultrasonic sensor reliably
02
Wire DRV8833 nSLEEP to 3.3V to keep the motor driver enabled
03
Connect ultrasonic trigger to GPIO13 and echo to GPIO14 for ranging
Reuse this netlist when assembling a small DC-motor robot with ESP32 Wi-Fi control and ultrasonic obstacle avoidance.
