International Power Adapters By MELIFE

• Module Properties: synchronous rectification non-isolated buck module, high conversion efficiency of 95%.
• Car power converter input voltage range is DC 9V-22V, output voltage range is DC 6V, output current is 3A, output power is 18W.
• Safe Protection: over-temp protection, over-current protection, over-voltage protection, input reverse connection protection, output short-circuit protection, surge protection, waterproof, dust-proof, shock-proof, moisture-proof.
• Special Features: the volt transformer is Waterproof, Dust-proof, Shockproof, Suitable for all kinds of harsh environments.
• Compatible With: car audio, motor, speaker, radio, auto LED display screen, photovoltaic panel, electric fan, solar power monitor, navigator, GPS navigation, industrial power supply etc.

• Power an electronic project or convert old hardware to use USB-C power input.
• Performs PD power negotiation. Supports up to 5A.
• Not all USB-C power supplies can support all voltages. If the power supply does not support the requested voltage then the next lowest voltage will be provided.
• The module just performs the PD negotiation and passes the output.
• Attention: In order to use it over 3A you need to use an electronically marked Type-C cable. A real USB PD power source is required, will not work with QC-only chargers.

• PERFECT FIT FOR ARDUINO: Fits perfectly on arduino board solderless breadboard and provides both 3.3V and 5V
• MULTIPLE POWER SUPPLY: The module provides dual 5 V and 3.3 V power rails, and has a multi-purpose female USB socket, convenient external lead use
• OUTPUT VOLTAGE SWITCHABLE: Fluctuation two road independent control, jumper pins are utilised for selecting the voltage levels on each side of the breadboard power rails. You can choose between 5V, OFF, and 3.3V
• SHORT CIRCUIT ALARM: The green power LED is connected to the output rail, when you applied a short to either of the voltage rails it would go out, this is an excellent indicator of a short in the power
• Uses a USB Type output port for control board and a voltage regulator chip 1117-5.0V/1117-3.3V

• High precision ADS1115 16 Bit 4 Channel Analog-to-Digital ADC Converter.
• Wide Voltage Supply Range: 2.0V to 5.5V, operate in a comparator mode which is helpful for maintaining accuracy.
• Continuous mode: Only 150uA is easy to implement, single mode: auto power off function, onboard reference and oscillator.
• Especially a good tool, there is no analog GPIO pin; Easy to use I2C ADC Converter, with Programmable Gain Amplifier.
• The ADS1115 is measured at high resolution and has an input multiplexer (MUX) that provides two programmble conparator differentials or four single-ended input; Four single-ended or ?256mV, allowing both large and small signals to be the differential input.

• High Precision: Featuring 36u thickened circuit boards and high-Q inductance, the buck converter comes equipped with an output LED indicator and superior solid-state capacitors, all of which work together to effectively filter out high frequency noise. This versatile unit is an ideal choice for various electronic projects.
• Easy to use: After connect to a power source, kindly use a mini screwdriver to adjust the screw located on the blue potentiometer, which allows you to either increase or decrease the output voltage. Use a multimeter to monitor the voltage and adjust the potentiometer accordingly until the desired voltage is reached. Remember to increment the voltage by turning the potentiometer clockwise, and decrease it by turning it counterclockwise.
• Product specifications: Input Voltage: DC 4V to 40V (input voltage must be 1.5V higher than the output voltage). Output Voltage: DC 1.25V to 37V voltage is continuously adjustable.
• Safety first: The switch features reverse voltage protection, over-temperature and short-circuit protection, thereby enhancing its safety usage significantly.
