The LilyPad Arduino is a microcontroller board designed for wearable and e-textiles. It can be sewn to fabric and similarly mounted power supplies, sensors and actuators with conductive thread. The board is based on the ATmega168V (the low-power version of the ATmega168).
Silent, energy efficient Quad-Core 64-bit Broadcom 2711, Cortex A72 processor :Raspberry pi run silently and saves more energy compared to other computers as it uses 20% less power compared to its previous versions.
RAM: 4 GB
USB 3: New Pi computer has an upgraded USB capacity with two more USB 3 port to with 10 times more transfer speed.
Fast networking: Raspberry Pi boards have gigabyte Ethernet, in addition to onboard wireless networking and Bluetooth.
Power: Micro USB-B is upgraded to Micro USB-C power connector which supports extra 500mA of current.
Dual Screen:Type-A HDMI cable is changed to pair of type-D HDMI connectors to enable dual monitor excess.
Arduino UNO has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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 an AC-to-DC adapter or battery to get started
