For retail orders, please Get Samples. Wholesale Orders If you order in bulk, the boards come in large cardboard boxes. For wholesale orders, please Contact Sales. Description of Components The following figure and the table below describe the key components, interfaces and controls of the ESP32-DevKitM-1 board. We take the board with a ESP32-MINI-1 module as an example in the following sections. ESP32-DevKitM-1 - front Key Component Description On-board module ESP32-MINI-1 module or ESP32-MINI-1U module. ESP32-MINI-1 comes with an on-board PCB antenna. ESP32-MINI-1U comes with an external antenna connector. The two modules both have a 4 MB flash in chip package. For details, please see ESP32-MINI-1 & ESP32-MINI-1U Datasheet. 5 V to 3.3 V LDO Power regulator converts 5 V to 3.3 V. Boot Button Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port. Reset Button Reset Button Micro-USB Port USB interface. Power supply for the board as well as the communication interface between a computer and the ESP32 chip. USB-to-UART Bridge Single USB-UART bridge chip provides transfer rates up to 3 Mbps. 3.3 V Power On LED Turns on when the USB is connected to the board. For details, please see the schematics in Related Documents. I/O Connector All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board. Users can program ESP32 chip to enable multiple functions. Start Application Development Before powering up your ESP32-DevKitM-1, please make sure that it is in good condition with no obvious signs of damage. Required Hardware ESP32-DevKitM-1 USB 2.0 cable (Standard-A to Micro-B) Computer running Windows, Linux, or macOS Software Setup Please proceed to Get Started, where Section Installation will quickly help you set up the development environment and then flash an application example onto your ESP32-DevKitM-1. Attention ESP32-DevKitM-1 boards manufactured before December 2, 2021 have a single core module installed. To verify what module you have, please check module marking information in PCN-2021-021 . If your board has a single core module installed, please enable single core mode with CONFIG_FREERTOS_UNICORE in menuconfig before flashing your applications. Hardware Reference Block Diagram A block diagram below shows the components of ESP32-DevKitM-1 and their interconnections. ESP32-DevKitM-1 Power Source Select There are three mutually exclusive ways to provide power to the board: Micro USB port, default power supply 5V and GND header pins 3V3 and 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. Power supply by micro USB port is recommended. Pin Descriptions The table below provides the Name and Function of pins on both sides of the board.
