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.
ESP32-PICO-KIT V3 board layoutBelow is the description of the items identified in the figure starting from the top left corner and going clockwise.
Key Component | Description |
---|---|
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. |
Before powering up your ESP32-PICO-KIT V3, please make sure that the board is in good condition with no obvious signs of damage.
After that, proceed to ../../get-started/index
, where Section get-started-step-by-step
will quickly help you set up the development environment and then flash an example project onto your board.
