The Silent Killer of Industrial Connectivity. In the world of manufacturing, automation, and data acquisition, reliable communication is non-negotiable. Many mission-critical systems still rely on the venerable RS232 serial standard to communicate with modern PCs, PLCs, and control systems. The solution seems simple: a cheap USB-to-RS232 converter. But if you work with industrial weighing scales, noisy factory floors, or complex data loggers, you know the truth: those inexpensive converters are a major headache. They drop connections, introduce errors, and often fail completely due to the harsh realities of the environment—namely, Electromagnetic Interference (EMI) and extreme conditions. If you’re tired of debugging intermittent data streams and replacing fragile cables, it’s time to upgrade to a solution built specifically for the factory floor. Introducing the Industrial-Grade Difference The Industrial USB to RS232 Converter by Graylogix is engineered not just to connect two protoco...

  Product Overview Fastest Finger First Quiz Buzzer System is a quiz buzzer that can handle up to 8 teams. When any team presses its switch, that player number is displayed on the seven segment LED display accompanied by the buzzer beep. When more than one team presses the switch, the delay is accurately taken into account and fastest first player number is displayed. Also this system is able to detect fastest finger first and sequence of switch pressed by other players. Finally, the quiz master can check the sequence of the players who have pressed the switch by pressing sequence switch and once the round is complete the quiz master can reset the system by pressing reset switch. Package Includes: • 1 x Buzzer module • 8 x Team switches (approx. 5 m length of cable each) • 1 x Quiz master reset switch (approx. 5 m length of cable) • 1 x Quiz master sequence switch (approx. 5 m length of cable) • 1x 230v power cord (approx. 10 m length of cable) • 1 x Copy of Quiz buzzer system manu...

  SIM A7670C 4G LTE TTL Modem is a Cat-1 Module which supports wireless communication modes of LTE-TDD/LTE-FDD subsequently. Basically It supports maximum 10Mbps downlink rate and 5Mbps uplink rate.  Generally AT instructions are used to communicate with the A7670C. The SIM A7670C 4G LTE TTL Modem Board is specifically designed keeping in mind the requirements of the user. It has various pinouts from the module, such as RING – used to detect incoming call, DTR – to use the 4G Module in ultra low power sleep mode, STATUS – to detect the status of 4G Module. NETLIGHT – in case developer wants to use external LED to indicate network status, RESET – developer can use this pin to connect with MCU and reset the module if required. It has onboard UART Logic Level Convertor and works on 5V TTL logic level as well as 3.3V TTL Logic level, By default its 5V TTL Logic level, in order to perform the board on 3.3V TTL Logic level please shift the 0E Resistor from 5V to 3.3V as depicted in ...

  Quectel L76 GPS receiver with Antenna is a concurrent receiver GNSS module in small formfactor with 33 tracking channels, 99 acquisition channels, and 210 PRN channels. The L76 can acquire and track any mix of 3 multiple satellite constellations, providing simultaneous GPS, GLONASS, BeiDou, Galileo and QZSS open service L1 reception capability. This increases the number of visible satellites and reduces time-to-first-fix, allowing accurate navigation in settings such as urban canyons. The L76 combines EASY™ (Embedded Assist System for self-generated orbit prediction) with LOCUS™ (internal logger) and AlwaysLocate™ to achieve excellent accuracy with low power consumption. EASY™ allows the module to calculate and predict orbits automatically using up to 3 days of ephemeris data stored in the RAM, so it can fix position quickly and with low power consumption, even when signal levels are lower. LOCUS™ allows the module to log position information to the internal flash memory at defau...
