Plug a USB cable with micro-B plug into the micro-USB socket on the board and the other end into a PC USB port to power up the board. The ESP32 Devkit board is powered from a micro-USB connector. This section contains the basic minimum information that anyone using the ESP32 Devkit board needs to know before starting to use it, test it or program it. DOIT ESP-WROOM-32 Devkit used in this Testing and First Use Tutorial ESP32 Devkit ESP-WROOM-32 Board Basic Hardware Information Some simple programs written in Lua are used to test the board to see if it is running.īelow is a top and bottom view of the board used in this tutorial. LuaNode is preloaded on the board allowing it to be programmed in the Lua programming language. The ESP32 Devkit board from DOIT is based on the ESP-WROOM-32 microcontroller from Espressif with integrated WiFi and Bluetooth.

It also shows how to install Windows drivers for the board and how to communicate with the board from a serial port terminal program in Windows and Linux. For details, see GPIO Header 1.This article shows how to do some basic initial tests to see if a new ESP32 Devkit board is working. This header provides six unpopulated through-hole solder pads connected to spare GPIOs of ESP32.

Holding down BOOT and then pressing EN initiates Firmware Download mode for downloading firmware through the serial port. Two LEDs (green and red) that respectively indicate the “Link” and “Activity” statuses of the PHY.ĭownload button. The magnetics also provide galvanic isolation between the transceiver and the Ethernet device. The Magnetics are part of the Ethernet specification to protect against faults and transients, including rejection of common mode signals between the transceiver IC and the cable. The PHY supports the IEEE 802.3/802.3u standard of 10/100 Mbps. The connection between PHY and ESP32 is done through the reduced media-independent interface (RMII), a variant of the media-independent interface (MII) standard. The physical layer (PHY) connection to the Ethernet cable is implemented using the IP101GRI chip. Provided DC 5 V to 3.3 V conversion, output current up to 2 A.Ī pair male and female header pins for mounting the PoE board (B) This red LED turns on when power is supplied to the board, either from USB or 5 V Input. The 5 V power supply interface can be more convenient when the board is operating autonomously (not connected to a computer). Toggling the switch to 5V0 position powers the board on, toggling to GND position powers the board off.
Power supply for the board as well as the communication interface between a computer and the board.
See ESP32-Ethernet-Kit V1.2 Ethernet board (A) schematic. The FT2232H chip enhances user-friendliness in terms of application development and debugging. FT2232H also features USB-to-JTAG interface which is available on channel A of the chip, while USB-to-serial is on channel B. The FT2232H chip serves as a multi-protocol USB-to-serial bridge which can be programmed and controlled via USB to provide communication with ESP32. Two LEDs to show the status of UART transmission. For details, see GPIO Header 2.Ī 4-bit DIP switch used to configure the functionality of selected GPIOs of ESP32. This ESP32 module features 64-Mbit PSRAM for flexible extended storage and data processing capabilities.įive unpopulated through-hole solder pads to provide access to selected GPIOs of ESP32.
