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.
SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...
The ESP32 is an example of a chip combining RF CMOS with digital logic, which in this case is one or two processor cores that are hidden. The baseband processors [ 20 ] [ 21 ] and radio transceivers in all modern wireless networking devices and mobile phones are mass-produced using RF CMOS devices. [ 14 ]
The following table compares official Arduino boards, and has a similar layout as a table in the Arduino Uno article. The table is split with dark bars into three high-level microcontroller groups: 8-bit AVR cores, 32-bit ARM Cortex-M cores, and 32-bit ESP32 microcontrollers.
Narrowband Internet of things (NB-IoT) is a low-power wide-area network (LPWAN) radio technology standard developed by 3GPP for cellular network devices and services. [1] [2] The specification was frozen in 3GPP Release 13 (LTE Advanced Pro), in June 2016. [3]
Camera PCB with a 1/3" Sony CCD Camera modules may include a lens (shown at top), an image sensor (shown at bottom), and supporting circuitry. NC393 multisensor camera kit, for developers. A camera module is an image sensor integrated with a lens, control electronics, [1] and an interface like CSI, Ethernet or plain raw low-voltage differential ...
Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection.
