  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...

  The MPS20N0040D Pressure Sensor HX710B is an Barometric and Sphygmomanometer Air Pressure Sensor module which receives data and transmits it to the HX710 IC, which is an ADC converter used to measure the ambient pressure and the pressure difference of liquid levels. The HX710 is a precision 24-bit analog to-digital converter (ADC) with built-in temperature sensor designed for weigh scales and industrial control applications to interface directly with a bridge sensor.

  WCS2720 Current Sensor 20A provides economical and precise solution for both DC and AC current sensing in industrial, commercial and communications systems. The unique package allows for easy implementation by the customer. Typical applications include motor control, load detection and management, over-current fault detection and any intelligent power management system etc. The WCS2720 consists of a precise, low-temperature drift linear hall sensor IC with temperature compensation circuit and a current path with 0.4 m typical internal conductor resistance. This extremely low resistance can effectively reduce power loss, operating temperature and increase the reliability greatly. Applied current flowing through this conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. The terminals of the conductive path are electrically isolated from the sensor leads. This allow the WCS2720 current sensor to be used in app...
