Check the complete physical system

ESP32 logic voltages and browser simulations do not reveal power-supply faults, loose wiring, mechanical failure, heat, interference, or unsafe behavior. Verify the exact board revision, pin map, supply, enclosure, load, and applicable local rules.

• Mains power: isolate the circuit and use qualified protection and enclosure practices. Never prototype exposed mains wiring.
• Lithium batteries: use a compatible charger, verified protection, correct polarity, fusing, and thermal design.
• Motors and actuators: guard moving parts, provide an independent stop, and size drivers and supplies for stall current.
• Radio equipment: follow local frequency, power, antenna, and licensing rules.
• Flashing: back up first, confirm the target board, and avoid unofficial images from untrusted sources.

检查完整实体系统

ESP32 逻辑电压及浏览器模拟无法反映电源故障、接线松动、机械失效、发热、干扰或危险行为。请核对准确板卡版本、引脚、供电、外壳、负载及适用的当地规定。

• 市电：必须隔离电路，使用合格的保护与外壳方案。不要搭建裸露的市电原型。
• 锂电池：使用兼容充电器、可靠保护、正确极性、保险与热设计。
• 电机与执行器：隔离运动部件，提供独立急停，并按堵转电流选择驱动与电源。
• 无线电设备：遵守当地频率、功率、天线及许可规定。
• 刷写：先备份，确认目标板型，不要使用来源不明的非官方镜像。

Stop when behavior is uncertain

Disconnect power if a device overheats, smells unusual, moves unpredictably, makes an unexpected radio transmission, or stops responding to safety controls. Obtain qualified help for mains, battery, high-current, or mechanical systems.

不确定时停止

设备过热、出现异味、异常运动、意外发射无线电或不再响应安全控制时，请立即断开电源。市电、电池、大电流或机械系统应寻求合格人员帮助。
