-
Microcontroller: ATmega328P (SMD)
-
Operating Voltage: 5V
-
Input Voltage (recommended): 7–12V
-
Digital I/O Pins: 14 (6 PWM outputs)
-
Analog Input Pins: 6
-
DC Current per I/O Pin: 20 mA
-
Flash Memory: 32 KB (ATmega328P)
-
SRAM: 2 KB
-
EEPROM: 1 KB
-
Clock Speed: 16 MHz
-
USB Connector: Type-B
-
Dimensions: 68.6 mm x 53.4 mm
This board is ideal for beginners and makers looking for a reliable development platform. The SMD version is more compact and cost-effective, but unlike the DIP version, the microcontroller is not easily replaceable.
