ESP32-PICO-KIT V4
|
||||
=================
|
||||
|
||||
This guide shows how to get started with the ESP32-PICO-KIT V4/V4.1 mini development board.
|
||||
|
||||
This particular description covers ESP32-PICO-KIT V4 and V4.1. The difference is the upgraded USB-UART bridge from CP2102 in V4 with up to 1 Mbps transfer rates to CP2102N in V4.1 with up to 3 Mbps transfer rates.
|
||||
|
||||
What You Need
|
||||
-------------
|
||||
|
||||
* :ref:`ESP32-PICO-KIT mini development board <get-started-pico-kit-v4-board-front>`
|
||||
* USB 2.0 A to Micro B cable
|
||||
* Computer running Windows, Linux, or macOS
|
||||
|
||||
Overview
|
||||
--------
|
||||
|
||||
ESP32-PICO-KIT 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 with complete Wi-Fi and Bluetooth functionalities. Compared to other ESP32 modules, ESP32-PICO-D4 integrates the following peripheral components in one single package, which otherwise would need to be installed separately:
|
||||
|
||||
- 40 MHz crystal oscillator
|
||||
- 4 MB flash
|
||||
- Filter capacitors
|
||||
- RF matching links
|
||||
|
||||
This setup reduces the costs of additional external components as well as the cost of assembly and testing and also increases the overall usability of the product.
|
||||
|
||||
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. For compatibility with Dupont wires, 2 x 17 header pads are populated with two rows of male pin headers. The remaining 2 x 3 header pads beside the antenna are not populated. These pads may be populated later by the user if required.
|
||||
|
||||
.. note::
|
||||
|
||||
1. There are two versions of ESP32-PICO-KIT boards, respectively with male headers and female headers. In this guide, the male header version is taken as an example.
|
||||
2. The 2 x 3 pads not populated with pin headers are connected to the flash memory embedded in the ESP32-PICO-D4 SiP module. For more details, see module's datasheet in `Related Documents`_.
|
||||

||||

* - Key Component
|
||||
- Description
|
||||
* - ESP32-PICO-D4
|
||||
- Standard ESP32-PICO-D4 module soldered to the ESP32-PICO-KIT 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: CP2102 in V4 provides up to 1 Mbps transfer rates and CP2102N in V4.1 offers up to 3 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.
|
||||
* - 5V Power On LED
|
||||
- This red LED turns on when power is supplied to the board. For details, see the schematics in `Related Documents`_.
|
||||
* - 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. For details, please see Section `Pin Descriptions`_.
|
||||
* - 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.
|
||||
|
||||
|
||||
Power Supply Options
|
||||
--------------------
|
||||
|
||||
There are three mutually exclusive ways to provide power to the board:
|
||||
|
||||
* Micro USB port, default power supply
|
||||
* 5V / GND header pins
|
||||
* 3V3 / GND header pins
|
||||
|
||||
.. warning::
|
||||
|
||||
The power supply must be provided using **one and only one of the options above**, otherwise the board and/or the power supply source can be damaged.
|
||||
|
||||
|
||||
Pin Descriptions
|
||||
----------------
|
||||
|
||||
The two tables below provide the **Name** and **Function** of I/O header pins on both sides of the board, see :ref:`get-started-pico-kit-v4-board-front`. The pin numbering and header names are the same as in the schematic given in `Related Documents`_.

|
||||
Where <config_name> is the name of board configuration you want to use, i.e.: nsh, buttons, wifi...
|
||||
Then use a serial console terminal like ``picocom`` configured to 115200 8N1.

The PSRAM CS IO can be any unused GPIO, user can config it based on

For ESP32-PICO chip, the psram share clock with flash, so user do

not need to configure the clock IO.

This value is ignored unless flash mode is set to DIO or DOUT and

the SPI flash pins have been overridden by setting the eFuses
|

SPI_PAD_CONFIG_xxx.
|
||||
|
||||
When this is the case, the eFuse config only defines 3 of the 4
|
||||
Quad I/O data pins. The WP pin (aka ESP32 pin "SD_DATA_3" or SPI
|
||||
flash pin "IO2") is not specified in eFuse. And the psram only
|
||||
has QPI mode, the WP pin is necessary, so we need to configure
|
||||
this value here.
|
||||
|
||||
When flash mode is set to QIO or QOUT, the PSRAM WP pin will be
|
||||
set as the value configured in bootloader.
|
||||
|
||||
For ESP32-PICO chip, the default value of this config should be 7.

|
||||
* Description:
|
||||
* Reset board. Support for this function is required by board-level
|
||||
* logic if CONFIG_BOARDCTL_RESET is selected.
|
||||
*
|
||||
* Input Parameters:
|
||||
* status - Status information provided with the reset event. This
|
||||
* meaning of this status information is board-specific. If not
|
||||
* used by a board, the value zero may be provided in calls to
|
||||
* board_reset().
|
||||
*
|
||||
* Returned Value:
|
||||
* If this function returns, then it was not possible to power-off the
|
||||
* board due to some constraints. The return value in this case is a
|
||||
* board-specific reason for the failure to shutdown.
