**3 units!** ATmega328P CH340 Mini-USB Board compatible with Arduino UNO IDE

3 UNITS - UNO Compatible board The same board that you love, with thinner profile! Mini-USB port makes it more compact, perfect for tight applications. This is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, this is the most robust board you can start playing with. This is the most used and documented board.  The UNO is a microcontroller board based on the ATmega328P.  It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), 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.   The board is the first in a series, and the reference model for the platform.   What's in the box: 3 boards with Mini-USB connector and pins.    Tech Specs:   Microcontroller   ATmega328P   Operating Voltage   5V   Input Voltage (recommended)   7-12V   Input Voltage (limit)   6-20V   Digital I/O Pins   14 (of which 6 provide PWM output)   PWM Digital I/O Pins     6   Analog Input Pins   6   DC Current per I/O Pin   20 mA   DC Current for 3.3V Pin   50 mA   Flash Memory   32 KB (ATmega328P) of which 0.5 KB used by bootloader   SRAM   2 KB (ATmega328P)   EEPROM   1 KB (ATmega328P)   Clock Speed   16 MHz   LED_BUILTIN   13   Length   68.6 mm   Width   53.4 mm   Weight   25 g
