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.
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 ...
A voice command device is a device controlled with a voice user interface. Voice user interfaces have been added to automobiles , home automation systems, computer operating systems , home appliances like washing machines and microwave ovens , and television remote controls .
It may also provide in-vehicle connectivity via Wifi and Bluetooth and implements the eCall function when applicable. In the automotive domain, a TCU can also be a transmission control unit. A TCU consists of: A satellite navigation (GNSS) unit, which keeps track of the latitude and longitude values of the vehicle
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 ...
Currently, cellular based on 3GPP-Release 16 [19] and WiFi based on IEEE 802.11p have proven to be potential communication technologies enabling connected vehicles. However, this does not negate that other technologies for example, VLC , ZigBee , WiMAX , microwave , mmWave are still a vehicular communication research area.
Radio-controlled cars, or RC cars for short, [1] are miniature vehicles (cars, vans, buses, buggies, etc.) controlled via radio. Nitro powered models use glow plug engines, small internal combustion engines fuelled by a special mixture of nitromethane , methanol , and oil (in most cases a blend of castor oil and synthetic oil ).
The operator gets a first-person perspective from an onboard camera that feeds video to FPV goggles or a monitor. [1] [2] More sophisticated setups include a pan-and-tilt gimbaled camera controlled by a gyroscope sensor in the pilot's goggles and with dual onboard cameras, enabling a true stereoscopic view.
