HiLetgo NodeMCU LUA WiFi Internet ESP8266 Development BoardESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.
Install an HDMI, VGA, mDP & Composite Audio/Video access panel into the surface of a table, and output to an HDMI display or projector, with a discreet hideaway design - The BOX4HDECP Automatic Conference Table Connectivity Box features a concealed, in-table design that lets you connect a VGA, Mini DisplayPort, HDMI or composite video source device to an HDMI display or projector. When the video switch isn't in use, you can simply slide the stylish cover panel over the connectors, hiding themÂ insideÂ the table or podium surface. Convenient Accessibility Presenters can conveniently share content from their own device withÂ the table top switch automatically convertingÂ any attached audio/video source deviceÂ source into a single HDMI output. The switch box also offers stylish integration into yourÂ modern boardroom or classroomÂ withÂ a discreet hideaway panel.Â For added convenience the BOX4HDECP features aÂ USB charging port to charge your mobile deviceÂ and an Ethernet pass-through port for Internet connectivity in boardrooms whereÂ Wi-Fi is not available. Connectivity Options With support for different video inputsÂ including: HDMI,Â VGA, Mini DisplayPort, and composite, the video switch ensures support for almost any laptop, Ultrabook or mobile deviceÂ such asÂ MacBook, Microsoft Surface Pro 2 & 3,Â and Lenovo X1. The switch panel even works withÂ legacy audio/video devices such as DVD player, and supports the use of video adapters for your iPhone orÂ iPad. Collaborate Easily The A/V switch makes your large display accessibleÂ to anyÂ presenter's video source device, by installing directly into the surfaceÂ of yourÂ table or podium, andÂ automatically outputsÂ the most recently connected video source.Â Plus, support for high-definition video resolutions up to 1920x1080 (1080p) ensures the quality of your presentation isÂ maintained. The BOX4HDECP is backed by a StarTech.com 2-year warranty, and free lifetime technical support.
the TEG-MGBSX Mini-GBIC Multi Mode module works with standard Mini-GBIC slots on most switches. This Multi-Mode LC Type module spans distances up to 550m (1,800ft) and includes 1 x 1000Mbps-SX (LC-Type) Mini-GBIC connector /p

Product Contents: â€¢ 2 pieces Addicore nRF24L01+ modules â€¢ 1 piece pink anti-static foam protecting pins of modules â€¢ 1 Addicore nRF24L01+ info card (includes pinout diagram) â€¢ 1 4mil thick resealable clear plastic bag Specifications: â€¢ The Addicore nRF24L01+ is a 2.4GHz ISM band transceiver. â€¢ Includes on board support components and a 2.4GHz antenna for easy implementation into designs without additional hardware. â€¢ Communication range 262 feet (80 meters) in ideal conditions. â€¢ A host microcontroller can communicate and configure the nRF24L01+ over a 4-pin Serial Peripheral Interface (SPI). The configuration registers are accessible through the SPI connection. Configurable parameters include frequency channel (125 selectable channels), output power, and data rate (data rates: 250kbps, 1Mbps, and 2Mbps). â€¢ The on chip voltage regulator accepts supply voltages from 1.9 to 3.6V. When using the nRF24L01+ with an Arduino be sure to use the 3.3V output pin from the Arduino board to power the nRF24L01+ module. â€¢ The module has 5V tolerant inputs which allows for direct connection of SPI pins to the Arduino. â€¢ Ultra low power consumption as low as 11.3mA transmitting, 13.5mA receiving at 2Mbps, 900nA in power down, and 26uA in standby. â€¢ Internal filtering results in high margins of meeting RF regulatory standards. The module's radio uses Gaussian Frequency-Shift Keying (GFSK) modulation as well as fast Automatic Gain Control (AGC). â€¢ The module includes an Interrupt Request (IRQ) pin which can be used to wake the host microcontroller, (ex: Arduino), from sleep when the module receives a transmission providing great power conservation in battery devices. â€¢ Auto-acknowledge and auto-retransmit.
