Weewooday 6 Pieces Nano Board V3.0 ATmega328P Without Cable Compatible with Arduino Nano V3.0 with Pin Headers Pin Unsoldered

Weewooday 6 Pieces Nano Board V3.0 ATmega328P Without Cable Compatible with Arduino Nano V3.0 with Pin Headers Pin Unsoldered

What you will get: the package included 6 pieces of nano board V3.0 ATmega328P, each nano V3.0 ATMEGA328P improved version with 3 pieces of pin headers unsoldered ATmega328P chips: using Atmega328P-AU MCU, support ISP download, using the same chips ATmega328P and CH340 with the official version Mini nano board: this is a portable, complete, and breadboard friendly board. It has everything that compatible with Arduino has (electrically) with more analog input pins and onboard +5V AREF jumper Input and output: each of the 14 digital pins on the Nano can be applied as an input or output. Some pins have special functions USB connection: the Nano can be powered via the Mini-B USB connection, 7-12V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically chosen to the high voltage source
Features:

Specifications:
Microcontroller: Atmega328P-AU MCU
Operating voltage (logic level): 5v
Input voltage (recommended): 7-12v
Digital I/O pins: 14 (of which 6 provide PWM output)
Analog input pins: 8
Direct current current per I/O Pin: 40 mA
Flash memory: 16 KB (ATmega168) or 32 KB (ATmega328) of which 2 KB used by bootloader
SRAM: 2 KB (ATmega328)
EEPROM: 1 KB (ATmega328)
Clock speed: 16 MHz

Notices:
The header pins haven't been soldered.
It lacks only a direct current power jack, and works with a Mini-B USB cable instead of a standard one.
The board is automatically sense and switch to the higher potential source of power, there is no need for the power select jumper.
