Curve tracer in hand, he set up an ESP-01 module to set a GPIO to input, and started increasing the voltage. The tests have shown that, while there’s a reverse biased ESD diode from GPIO pins to ground, there don’t seem to be diodes from the GPIO pin to the VCC rail – and ...
ESP8266-01资料汇总(1) 1、模块概述 模块管脚排列图 模块基本参数 Pin脚定义 功耗 下列功耗数据是基于3.3V的电源、25°的环境温度下测得。 [1] 所有测量均在天线接口处完成。 [2] 所有发射数据是基于 90% 的占空比,在持续发射的模式下测得的。 射频指标 以下数据是在室内温度下,电压为3.3V时测得。 注: ...

If ESP32, or ESP8266 can wake up from deep slep based on RX pin status, then i use ESP. If not i have to use a regular transceiver. What is all about. I have an RFID reader connected to an NodeMcu – ESP8266 RX pin. When i read a card, i send the numbers of the card to...
