The Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 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 or power it with a AC-to-DC adapter or battery to get started. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila.
The Raspberry Pi is a wonderful little computer that fits in the palm of your hand, yet packs enough power to run your home media center, a VPN, and a lot more.The Raspberry Pi 3 Model B + is the latest product in the Raspberry Pi3 family, with a 1.4 GHz quad-core 64-bit processor, 2.4GHz and 5GHz dual-band wireless network, Bluetooth 4.2 / BLE connection, a faster Ethernet connection and the possibility of PoE connection via a separate HAT PoE .
It has an easy to read 4 digit LED is used to display the voltage and current values and 4 programmable storage setting.This is a heavy duty single-channel, constant-voltage and constant-current Linear power supply with low ripple and noise, high reliability and high accuracy.The voltage and current are continuously adjustable.
A digital multimeter (DMM) is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance(ohms). The new generation of UT136+ series digital multimeter has an innovative industrial design which ensures that the product can withstand a drop of 2 meters height. Large LCD screen provides a clear display and its 4 times/second sampling rate provides users with more accurate readings. It is a standard diagnostic tool for technicians in the electrical/electronic industries.
