Quad-Band LTE Cat-M1 / NB-IoT Cellular Module with GNSS – Ultra-low-power cellular communication module designed for IoT devices, smart meters, asset tracking, industrial automation, telematics, smart cities, environmental monitoring, and embedded wireless applications. The SIMCom SIM7070G supports LTE Cat-M1, NB-IoT (Cat-NB2), and 2G GSM/GPRS fallback, providing global connectivity for low-power wide-area (LPWA) applications. It integrates multi-constellation GNSS support, including GPS, GLONASS, BeiDou, Galileo, and QZSS, enabling accurate positioning and tracking. Operates from a 3.4 V to 4.2 V supply, supports UART, USB 2.0, I²C, GPIO, ADC, PWM, and SIM interfaces, and offers low power consumption with PSM and eDRX modes for extended battery life. Packaged in a compact LCC + LGA module (24 × 24 mm), it is specified for −40°C to +85°C operation, making it ideal for rugged industrial and embedded IoT deployments. #SIMCom #SIM7070G #LTECatM1 #NBIoT #GNSS #CellularModule #IoT #AssetTracking #Telematics #IndustrialAutomation #EmbeddedWireless #EmbeddedSystems

8-Channel High-Side Source Driver Array – High-voltage, high-current source driver IC designed for LED and lamp driving, relay control, solenoid driving, industrial automation, printers, automotive electronics, PLCs, and embedded control systems. The Allegro UDN2981A integrates eight non-inverting high-side Darlington transistor outputs, allowing direct interfacing between TTL/CMOS logic and higher-voltage loads. Each output can source up to 500 mA, with an output voltage capability of up to 50 V, making it ideal for driving inductive and resistive loads. Features integrated input resistors, output clamp diodes for inductive load protection, and TTL/5 V CMOS-compatible inputs, simplifying circuit design and reducing external component count. Operates from a 4.75 V to 15 V logic supply, over a −20°C to +85°C temperature range, and is housed in an 18-pin DIP (through-hole) package for easy PCB integration. #Allegro #UDN2981A #HighSideDriver #SourceDriver #DarlingtonArray #RelayDriver #SolenoidDriver #LEDDriver #IndustrialAutomation #EmbeddedSystems #PowerDriver #TTLCompatible
