ESP32-PICO-KIT V3 Getting Started Guide¶
This guide shows how to get started with the ESP32-PICO-KIT V3 mini development board. For the description of other ESP32-PICO-KIT versions, please check ESP32 Hardware Reference.
What You Need¶
- ESP32-PICO-KIT V3 mini development board
- USB 2.0 A to Micro B cable
- Computer running Windows, Linux, or macOS
You can skip the introduction sections and go directly to Section Start Application Development.
ESP32-PICO-KIT V3 is an ESP32-based mini development board produced by Espressif. The core of this board is ESP32-PICO-D4 - a System-in-Package (SiP) module.
The development board features a USB-UART Bridge circuit, which allows developers to connect the board to a computer’s USB port for flashing and debugging.
All the IO signals and system power on ESP32-PICO-D4 are led out to two rows of 20 x 0.1” header pads on both sides of the development board for easy access.
The following figure and the table below describe the key components, interfaces, and controls of the ESP32-PICO-KIT V3 board.
Below is the description of the items identified in the figure starting from the top left corner and going clockwise.
|ESP32-PICO-D4||Standard ESP32-PICO-D4 module soldered to the ESP32-PICO-KIT V3 board. The complete ESP32 system on a chip (ESP32 SoC) has been integrated into the SiP module, requiring only an external antenna with LC matching network, decoupling capacitors, and a pull-up resistor for EN signals to function properly.|
|LDO||5V-to-3.3V Low dropout voltage regulator (LDO).|
|USB-UART bridge||Single-chip USB-UART bridge provides up to 1 Mbps transfers rates.|
|Micro USB Port||USB interface. Power supply for the board as well as the communication interface between a computer and the board.|
|Power On LED||This red LED turns on when power is supplied to the board.|
|I/O||All the pins on ESP32-PICO-D4 are broken out to pin headers. You can program ESP32 to enable multiple functions, such as PWM, ADC, DAC, I2C, I2S, SPI, etc.|
|BOOT Button||Download button. Holding down Boot and then pressing EN initiates Firmware Download mode for downloading firmware through the serial port.|
|EN Button||Reset button.|
Start Application Development¶
Before powering up your ESP32-PICO-KIT V3, please make sure that the board is in good condition with no obvious signs of damage.
