ESP32 development board
ESP32 development board introduction
The ESP32 development board is a low-cost, low-power system-on-chip microcontroller circuit board that integrates WIFI and dual-mode Bluetooth, it is mainly used to develop and test the ESP32 development board WIFI + Bluetooth function.
Wi-Fi supports a wide range of communication connections, and also supports direct connection to the Internet through routers; while Bluetooth allows users to connect mobile phones or broadcast BLE Beacon for signal detection.
The sleep current of the ESP chip in the ESP32 development board WIFI + Bluetooth is less than 5mA, making it suitable for ESP32 development board battery-powered wearable electronics. The data transmission rate supported by the ESP32 development board is up to 150Mbps, and after passing through the power amplifier, the output power can reach 22dBm, which can realize a wide range of wireless communication. Therefore, this ESP32 development board for sale has leading technical specifications and excellent performance in terms of high integration, wireless transmission distance, power consumption and network connectivity.
The operating system of the ESP32 development board is FREERTOS with LWIP and built-in TLS1.2 with hardware acceleration. Moreover, the ESP32 chip also supports OTA encryption upgrade, and developers can continue to upgrade after the product is released. As a low-cost WIFI/Bluetooth combo radio, the ESP32 development board with WIFI and Bluetooth is very popular not only among hobbyists, but also among IOT developers.
ESP32 dev board layout—The relationship between ESP32 chip, ESP32 module and ESP32 development board
ESP32 chip
provides ESP32 development board WIFI + Bluetooth function.
It only “defines” the function of the chip pins, and does not lead out the pins.
ESP32 development board external antenna material, size, function, etc. customization
ESP32 module
Some ESP32 dev board GPIO related to the WIFI function in the chip are drawn out and made into external pins for development and debugging, and docking with the product.
ESP32 development board
Provide download interface during debugging, connect ESP32 dev board LED/LCD screen, quickly feedback learning and test results, and get software code that meets expectations.
The product burns the code saved by the development board during the debugging phase into the corresponding module, and embeds the module into the product
