keyestudio Uno R3 is a microcontroller board based on the ATmega328

Development board for Arduino & Scratch.
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, 
a USB connection, a power jack, an ICSP header, and a reset button. 

 

Arduino advanced study kit walks you through the basics of using the Arduino in a hands-on way. 
You'll learn through building several creative projects. 
The kit includes a selection of the most common and useful electronic components with a book of 28 projects. 
Starting the basics of electronics, to more complex projects, the kit will help you control the physical world with sensor and actuators.

Keyestudio Mega (core to ATmega2560) is a development board (used with16MHz crystal oscillator) of microcontroller.

There 54 groups of I/O (input/output ) digital ends (of which 14 group to do PWM output),
