USB Cable A Male to Type B printer is a USB male head used to connect the computer’s USB interface; the other end is the mouth of the mouth, for connecting a USB printer, Arduino Uno boards, and Arduino Megas.

This is a Digital PWM Solar Charge Controller for the lead-acid batteries connected to a solar power system. When connected to the battery, this charge controller automatically detects the battery voltage from 12V-24V. This charge controller has some advanced features like built-in short circuit protection, open-circuit protection, reverse voltage protection, overload protection, etc which makes it ideal for grid power systems.

Arduino Uno r3 is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable A male to type B or power it with an AC-to-DC adapter or battery to get started.
