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 ...
Harbor Freight Tools, commonly referred to as Harbor Freight, is an American privately held tool and equipment retailer, headquartered in Calabasas, California. It operates a chain of retail stores, as well as an e-commerce business. The company employs over 28,000 people in the United States, [5] and has over 1,500 locations in 48 states. [6] [7]
Depending on distance and construction materials, one or more wireless repeaters may be required to bring the signal to the alarm panel reliably. A wireless system can be moved to a new property easily. An important wireless connection for security is between the control panel and the monitoring station.
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 name "NodeMCU" combines "node" and "MCU" (micro-controller unit). [8] Strictly speaking, the term "NodeMCU" refers to the firmware rather than the associated development kits. [citation needed] Both the firmware and prototyping board designs are open source. [8] The firmware uses the Lua scripting language. The firmware is based on the eLua ...
[citation needed] With the use of non-CTL breakers, panels can be configured with the total number of circuits in excess of the designed capacity of that panel. The 2008 code did away with the previous 42 circuit limitation on panelboards. [3] One can now order panelboards with as many as 84 circuit places, and a corresponding ampacity rating.
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.
A "dumb" ETD can be as simple as a red flag attached to the coupler on the last car of the train, whereas "smart" devices monitor functions such as brake line pressure and accidental separation of the train using a motion sensor, functions that were previously monitored by a crew in the caboose. [1]
