ESP32-PICO-KIT V4.1 Mini Development Board ESP32

Description:

ESP32-PICO-KIT V4.1 is a mini development board produced by Espressif. At the core of this board is the ESP32-PICO-D4, a System-in-Package (SIP) module with complete Wi-Fi and Bluetooth functionalities. Comparing to other ESP32 chips, the ESP32-PICO-D4 integrates several peripheral components in one single package, that otherwise would need to be installed separately. This includes a 40 MHz crystal oscillator, 4 MB flash, filter capacitors and RF matching links in. This greatly reduces quantity and costs of additional components, subsequent assembly and testing cost, as well as overall product complexity.

ESP32-PICO-KIT V4.1 Mini Development Board ESP32

The development board integrates a USB-UART Bridge circuit, allowing the developers to connect the board to a PC’s USB port for downloads and debugging.

Here following options are available to provide power supply to the ESP32-PICO-KIT V4.1:

Micro USB port, this is default power supply connection
5V / GND header pins
3V3 / GND header pins

Package Included

1 X ESP32-PICO-KIT V4.1 Mini Development Board

ESP32-PICO-D4

Standard ESP32-PICO-D4 module soldered to the ESP32-PICO-KIT V4.1 board. The complete system of the ESP32 chip has been integrated into the SIP module, requiring only external antenna with LC matching network, decoupling capacitors and pull-up resistors for EN signals to function properly.

LDO

5V-to-3.3V Low dropout voltage regulator (LDO).

USB-UART Bridge

A single chip USB-UART bridge provides up to 1 Mbps transfers rates.

Micro USB Port

USB interface. It functions as the power supply for the board and the communication interface between PC and ESP32-PICO-KIT V4.1.

5V Power On LED

This light emitting diode lits when the USB or an external 5V power supply is applied to the board. For details see schematic in Related Documents.

I/O

All the pins on ESP32-PICO-D4 are broken out to the pin headers on the board. Users 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

Holding down the Boot button and pressing the EN button initiates the firmware download mode. Then user can download firmware through the serial port.

EN Button: Reset button; pressing this button resets the system.

For easy interfacing, all the IO signals and system power on ESP32-PICO-D4 are led out through two rows of 20 x 0.1” pitch header pads on both sides of the development board.
To make the ESP32-PICO-KIT V4.1.1 fit into mini breadboards, the headerpads are populated with two rows of 17 pin headers.
Remaining 2 x 3 pads grouped on each side of the board besides the antenna are not populated.
The remaining 2 x 3 pin headers may be soldered later by the user
