In the third week of my project, I dedicated time to thoroughly studying the ESP32 microcontroller and came across a wealth of fascinating information. During my research, I delved deeper into the subject and discovered various modules that utilize the ESP32 chip. Some notable modules include the 12-E NodeMCU Kit, the WeMos D1 Mini, and the ESP-01. To provide a comprehensive overview, here is a list of specifications commonly found in ESP32 boards: Microcontroller: ESP32 (dual-core, 32-bit) Processor: Xtensa LX6 (up to 240 MHz) Wi-Fi: 802.11 b/g/n Bluetooth: Bluetooth 4.2, Bluetooth Low Energy (BLE) RAM: Typically ranging from 520KB to 4MB (internal) Flash Memory: Varies between 4MB to 16MB (internal) GPIO Pins: Multiple pins for digital input/output, analog input, PWM, SPI, I2C, etc. ADC: 12-bit ADC (analog-to-digital converter) DAC: 8-bit DAC (digital-to-analog converter) Voltage Range: 2.2V to 3.6V Operating Voltage: 3.3V Operating Temperature: -40°C to 125°C Additional Features: Ca...
