BangGood.com - ATmega328P Nano V3 Controller Board Compatible Arduino Improved Version [SKU157951]

Arduino nano clone.

You can see/buy it here: >> LINK <<

UPDATE:
I can make a simple scheme that can be used to test all the pins (digital I/O, PWM, analog IN), if someone is interested just leave a comment below.

Specifications:

• Microcontroller Atmel ATmega328
• Operating Voltage (logic level): 5V
• Input Voltage (recommended): 7V ~ 12V
• Input Voltage (limits): 6V ~ 20 V
• Digital I/O Pins: 14 (of which 6 provide PWM output)
• Analog Input Pins: 8
• Current per I/O Pin: 40mA (max) 20mA (recommended)
• Flash Memory: 32KB (ATmega328) (of which 2 KB used by bootloader)
• SRAM: 2KB (ATmega328)
• EEPROM: 1KB (ATmega328)
• Clock Speed: 16MHz

The image is huge, open it in another tab !

This module price is (currently) 3.27$ (around 3€).
The soldering quality is high, i can't see any defect.
The ATMEGA is an ATmega328P, the voltage regulator is a AMS1117 and the USB/SERIAL converter is a CH340G. The four leds are all RED.
I recommend to download the datasheet and the pinout pdf for more info.

WARNING!
I can't find how much the CH340G can output on the 3.3v, with google i've found two values, 50 mA and 120mA, to stay safe i suggest to not go more than 50 mA.
I asked directly to BangGood, the CH340G can supply max 50 mA on the 3.3v, don't exceed this limit !

Drivers/IDE HowTo:

Yellow triangle in the win7 driver panel.

 

Double click on the drivers (CH340-341.EXE), click INSTALL.

The driver is correctly installed on COM18 (this depends on your system).

Modify the Arduino IDE like this (COM18 can be different on your system).
