Description of ๐Ÿ”Œ Ultra-Compact Nano V3.0 ATmega328P Micro Controller Board with CH340G Chip โ€“ 5pcs Set Including Mini USB Cable

Nano V3. 0 ATMEGA328P Improved version with 3pcs pin headers soldered (2pcs 15pin headers +1pcs 6pin headers). The Nano is a compact board similar to the UNO.The Nano is a small, complete, and breadboard-friendly board based on the ATmega328P (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. The Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source. Each of the 14 digital pins on the Nano can be used as an input or output.They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions. The Nano has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers.Such as UART TTL (5V) serial communication and I2C (TWI) and SPI communication.

good computers and accessories

they arrived on time and all passed the usb code boot test. as stated in other comments for the Arduino 1.8.13 program as duemilanove or diecimila. Might need drivers for ch340G Win10 update? There are a few solder marks on the connectors and a few dents on the circuit boards, but it all looks cosmetic so I don't mind. came in a box individually wrapped in sealed Mylar with pins pressed in protective foam. 10/10 packaging

Pros
  • do not waste too much time
Cons
  • there are defects

[Atmega328P Nano (OLD LOADER)]

Working - After selecting [Atmega328P Nano (OLD BOOT)] in Arduino IDE 1.8.13. Didn't use an AVR to put a new bootloader in them to see if they take it? But when you select the OLD LOADER in your IDE, it becomes available for code entry. I ended up using it to create a USB serial data logger from a Harborfreight voyage sensor for automated testing.

Pros
  • Great selection
Cons
  • Sad packaging

They are listed as Nano but only work as Duemilanove

The website says Nano and they replace Nano but are not programmed as Nano. You must select "Arduino Duelmilanove". I'm still testing them but they seem to work great after I settled on "Arduino Duelmilanove". Introducing Blink, UltraSonic design, Introducing I2C design with one as master and the other as slave. worked fine. would buy again. All you have to do is put them in the shopping cart marked "Arduino Duelmilanove".

Pros
  • Easy to use
Cons
  • 0

He says they are nano but they only work as duemilans

The website says nano and they are in nano footprint but they are not programmed as nano. You must select "Arduino Duelmilanove". I'm still testing them but they seem to work great after I settled on "Arduino Duelmilanove". Introducing Blink, UltraSonic design, Introducing I2C design with one as master and the other as slave. worked fine. would buy again. All you have to do is put them in the shopping cart marked "Arduino Duelmilanove".

Pros
  • They bring joy
Cons
  • Modernity

They work and my students are happy

They were purchased for a class where my students are connecting a sensor to a mechanical device to record data for further calculations. I wanted to make this as easy as possible by giving each student a single set of electronics, with low cost being a top priority. I'm happy to report that all 5 boards are up and running with no issues. Make sure you select the board type as Duemilanove in the Arduino IDE and make sure you are using the correct serial port (COM for all Windows users).

Pros
  • Well built
Cons
  • 0

Read Christopher Hill's review if you're having trouble downloading programs from the IDE.

. I loaded the drivers for the CH340 chip and my computer "saw" the board, but the IDE still didn't load the sketch. I'm new to this area so I did some digging. I saw in 1 star that I was not alone. Then I read a review by Christopher Hill. He said to use the "Old Bootloader" option in the IDE and it worked great! These nanos are probably Chinese clones of clones and you probably wouldn't have the same issues with the more expensive nanos, but 5 for less than $20? The extra "work" was worth it.

Pros
  • . Don't waste too much time.
Cons
  • . Clarity

Works like Dumilans in Arduino ide

These work fine. They weren't recognized as Arduino nano by the Arduino ide, but they work if you set the board to duemilanove and the serial port to ttyUSB0 in the ide on the Raspberry Pi (and possibly other Linux distributions). Also, if you are using a raspberry pi, you should download the official ide from arduino.cc instead of installing it via apt. The Arduino ide version for the Raspbian repository is incomplete. The headers are pre-soldered so I ordered them. They're great for miniโ€ฆ

Pros
  • Pretty package
Cons
  • Can't remember
