N-Channel 30 V 5.7A (Ta) 1.4W (Ta) Surface Mount SOT-23-3 The AO3400A N-Channel MOSFET is a 30V N-channel enhancement-mode MOSFET designed using trench MOSFET technology. It is widely used for load switching, DC-DC converters, motor driving, and PWM control applications due to its very low on-resistance and compact SOT-23 package. It is especially popular in small electronics and embedded systems because it can be driven directly by 3.3V or 5V logic signals, making it ideal for microcontroller-based designs. Key Features Drain-Source Voltage (VDS): 30V Continuous Drain Current (ID): up to 5.7A (at 25°C) Ultra-low RDS(on): ~26.5 mΩ @ VGS = 10V ~32 mΩ @ VGS = 4.5V ~48 mΩ @ VGS = 2.5V Logic-level gate drive (works well with MCU GPIOs) Fast switching performance (ns-range switching times) Low gate charge (~6–7 nC) → efficient switching Compact SOT-23 package for space-saving PCB design Low power dissipation (~1.4W typical at 25°C ambient) Operating temperature: −55°C to +150°C Typical Applications Load switching (LEDs, sensors, small motors) Power management in battery-powered devices DC-DC converters PWM control circuits Fan and heater control in embedded systems #AO3400A #MOSFET #NChannelMOSFET #PowerElectronics #SOT23 #LoadSwitch #EmbeddedSystems #ElectronicsComponents #TrenchMOSFET #Commonpartslibrary #Transistor #FET

Accelerometer X, Y, Z Axis ±2g, 4g, 8g, 16g 0.05Hz ~ 1.6kHz 14-LGA (3x5) The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Free-fall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins. An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation. The ADXL345 is supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-lead, plastic package. ► Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical) ► Power consumption scales automatically with bandwidth ► User-selectable resolution ► Fixed 10-bit resolution ► Full resolution, where resolution increases with g range, up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor in all g ranges) ► Embedded memory management system with FIFO technology minimizes host processor load ► Single tap/double tap detection ► Activity/inactivity monitoring ► Free-fall detection ► Supply voltage range: 2.0 V to 3.6 V ► I/O voltage range: 1.7 V to VS ► SPI (3- and 4-wire) and I2C digital interfaces ► Flexible interrupt modes mappable to either interrupt pin ► Measurement ranges selectable via serial command ► Bandwidth selectable via serial command ► Wide temperature range (−40°C to +85°C) ► 10,000 g shock survival ► Pb free/RoHS compliant #commonpartslibrary #sensor #transducer #accelerometer

The Wio-E5-LE mini Dev Board integrates and provides access to the full GPIO capabilities of the Wio-E5-LE Wireless Module (STM32WLE5JC). With support for long range protocols and global frequencies, the Wio-E5-LE mini can achieve a transmission range up to 10km in open areas. It supports EU868 and US915, making it well-suited for wireless sensor networks and other IoT devices requiring battery power, low power consumption, and long range connectivity.

The Grove - CO2 & Temperature & Humidity Sensor (SCD30) is a high precision carbon dioxide sensor, which is based on Sensirion SCD30. The measuring range of this sensor is 0 ppm-40'000 ppm, and the measurement accuracy can reach to ±(30 ppm + 3%) between 400ppm to 10'000ppm.

The NE555 devices are precision timing circuits capable of producing accurate time delays or oscillation. In time-delay or monostable operating modes, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle are controlled independently with two external resistors and a single external capacitor. Each timer has a trigger level equal to approximately one-third of the supply voltage and a threshold level equal to approximately two-thirds of the supply voltage. These levels can be altered by use of the control voltage pin (CONT). When the trigger input (TRIG) is less than the trigger level, the flip-flop is set and the output goes high. If TRIG is greater than the trigger level and the threshold input (THRES) is greater than the threshold level, the flip-flop is reset and the output is low. The reset input (RESET) overrides all other inputs and is used to initiate a new timing cycle. If RESET is low, the flip-flop is reset and the output is low. Whenever the output is low, a lowimpedance path is provided between the discharge pin (DISCH) and the ground pin (GND). Tie all unused inputs to an appropriate logic level to prevent false triggering. The output circuit is capable of sinking or sourcing current up to 200mA. Operation is specified for supplies of 5V to 15V. With a 5V supply, output levels are compatible with TTL inputs. Features - Timing from microseconds to hours - Astable or monostable operation - Adjustable duty cycle - TTL-compatible output can sink or source up to 200mA - On products compliant to MIL-PRF-38535, all parameters are tested unless otherwise noted. Applications - Pulse-shaping circuits - Missing-pulse detectors - Pulse-width modulators - Pulse-position modulators - Sequential timers - Pulse generators -F requency dividers - Industrial controls
