However, these two areas are where the Arduino Mega shines. It's built with 256 ... Some boards like MKR1000 WiFi, Zero, and Nano 33 BLE Sense also have PWM support on some of their analog pins ...

When you think of Arduino ... There's the 53x101 mm Mega 2560 with 54 digital I/O pins, the 53x68 mm Zero with 32-bit low-power ARM processor, and the 25x61 mm MKR1000 WIFI with built-in Wi ...

It’s a significant update. The Arduino UNO and Arduino Mega 2560 update the Duemilanove and Mega respectively. They now use an ATMega8U2 instead of an FTDI USB to serial converter chip.
