The ESP32 V1.0 with a Type-C interface.

This description refers to a specific development board that combines the popular ESP32 microcontroller with a modern USB Type-C connector for power and programming.

What is it?

The ESP32-DevKitC-V1  is a compact development board from Espressif Systems, the creators of the ESP32 chip. The "V1.0" refers to the version of this specific board design. The key upgrade you're noting is that newer revisions or third-party manufacturers have replaced the older micro-USB connector with a newer, more reversible USB Type-C connector.

Key Features and Components

1. Core Chip: ESP32-WROOM-32 module. This is the brains of the board, containing:

   • Dual-Core Processor: Two Tensilica LX6 cores, running at up to 240 MHz.

   • Wireless Connectivity: Wi-Fi (802.11 b/g/n) and Bluetooth (Bluetooth Classic and BLE).

   • Memory: Typically 4MB of SPI Flash, 520KB of SRAM.

2. USB Interface: The Type-C port is used for:

   • Power: 5V power input to the board's voltage regulator.

   • Programming: Flashing new firmware from your computer (via the built-in USB-to-UART chip).

   • Communication: Serial communication (UART) to send and receive data with a computer.

3. USB-to-UART Bridge: A chip (like the CP2102 or CH340C) that translates data between the USB port and the ESP32's serial pins. This is essential for programming.

4. Voltage Regulator: Converts the 5V from the USB port down to the 3.3V required by the ESP32.

5. I/O Breakout Pins: All the GPIO (General Purpose Input/Output) pins of the ESP32 are broken out to the sides of the board, allowing you to connect sensors, displays, motors, and other peripherals.

6. Buttons:

   • Boot Button: Used to put the chip into firmware upload mode.

   • Reset Button: Restarts the microcontroller.
