ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...
NodeMCU DEVKIT 1.0, bottom. NodeMCU is a low-cost open source IoT platform. [4] [5] It initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module.
Apps does not require repeated built-in third-party dependencies, such as Chromium, Unity and Unreal Engine. This can greatly reduce the system ROM volume. [20] Harmony Distributed File System (HMDFS) is a distributed file system designed for large-scale data storage and processing that is also used in openEuler.
Designers may couple cores in a multi-core device tightly or loosely. For example, cores may or may not share caches, and they may implement message passing or shared-memory inter-core communication methods. Common network topologies used to interconnect cores include bus, ring, two-dimensional mesh, and crossbar.
A Bluetooth earbud, an earphone and microphone that communicates with a cellphone using the Bluetooth protocol. Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs).
