ESP32-PICO-KIT V3 Getting Started Guide
docs: Functional renaming commit for CMake-as-default Rename all the files which will be edited substantially in the next commit, without changing their contents Docs will not build for this ocmmit. This is done so that git doesn't decide we renamed xxx-cmake -> xxx-legacy in the next commit, which is what it will infer otherwise (and makes rebasing more of a pain than it should be)

Overview

2019-03-26 08:11:11 +00:00
ESP32-PICO-KIT V3 is an ESP32-based mini development board produced by `Espressif <https://espressif.com>`_. 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.

Below 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.
