Title: [Review] The cheapest Arduino Uno R3 compatible: VISduino
Post by: Peter_n on Jan 27, 2015, 05:44 pm
Hi,
I bought the cheapest Arduino Uno R3 compatible board for less than 5 dollars/euros, and this is a small review.
The usb-serial chip is a CH340G, that requires an extra driver to be installed (ch341ser.exe from wch.cn).

Plus


Minus


Conclusion

Pro: (From the photo) it appears to use a crystal rather than a resonator.

Con: It is a SMD processor, so if you blow it up, it will be hard to replace. But for that price, who cares?
Con: It doesn't look like you can flash the USB chip, but again, that probably doesn't matter.

The name VISduino is on the pcb, it was not mentioned on Ebay when I bought it.
Search on Ebay for : arduino uno r3
Select: buy it now
Sort for lowest price for item plus shipping.
Look for the yellow board. My board was not shipped to every country.

The CH340G is used for usb-serial. It just does its job without complaining.

This is at the moment the cheapest Uno R3 compatible board on Ebay.com, and it is a yellow one : http://m.ebay.com/itm/390966031687

Change the 'm.ebay.com' into 'www.ebay.com.au'. The exclude list has "AUS"... :(

Well, it works both ways. I tried to buy Vegemite, and it is hard to get in Europe, and has high shipping costs. So I ended up eating two jars Marmite.

Taxes and/or postal delivery problems are the only things I can think of.

However, your government (like most) does have some oddball restrictions...

Quote
The Australian Government controls the import of certain goods into Australia. The controls include:
- an absolute prohibition, where you are not allowed to import the goods in any circumstances, or
- a restriction, where you need to have written permission in order to import the goods.

...

Goods bearing an image of the Australian national flag and coat of arms (restricted import)

Items or merchandise (such as souvenirs) containing or which apply a representation of the coat of arms, a flag or a seal of the Commonwealth. This includes a representation closely resembling the coat of arms, a flag or a seal of the Commonwealth, which may be taken as a true 'national symbol'.

Shipping to Australia is often more expensive than to us or eu.

I live in Europe and I bought that VISduino board, not because I needed it, but only to see what the cheapest Arduino Uno compatible is like.

I'm sorry, I forgot that the improved forum has two "(Add Karma)" links on the left of each person's post, but they removed the part that stated what country a poster lived in.

I'm from Australia, the land of Vegemite.

Strange Chinese rules!
Ali Express told me they couldn't send a 12V 6A PSU to the UK, when I tried to order it.
BangGood sent the same item, at a similar price (only a few pennies difference), without any problems???

I ordered one of these back in December, it just arrived.
It shipped without an issue to Greece.

Got it from ebay, http://www.ebay.com/itm/291293761956

Seems to work without an issue so far. Not that I have done anything grand with it yet, just flashing leds and beeps so far.
It is recognised as an arduino uno by the arduino software.

Deal Extreme now offers this (unbranded) or a copy of it for US$ 6,30 / € 5,57.
Traces look very similar, so do the components (as far as visible in the pictures).
Just the VISduino text isn't in the silkscreen.

A while ago when I wanted to buy a processor board from the UK (I don't remember which, but something like an Atmega2560) I had to fill out a declaration form that it wasn't going to be used for terrorism.

Quite apart from the fact that genuine terrorists might be tempted to, ah, lie on such a form, I can easily buy equally powerful processors in Australia, on eBay, from the USA, etc.

So I'm not sure what useful purpose this document served.

But I've bought an Arduino Mega clone from China and loads of other stuff. 
In fact, a packet of 5 hook probes arrived from there today.
The only explanation I can think of is that the supplier has had trouble sending stuff here previously.
It may be because it isn't marked with the WEEE* mark, but that would apply in every EC country.
* EC Waste Electronic and Electrical Equipment regulations mark. Just a waste bin with a cross over it, indicating that it shouldn't be put in with general waste.

I bought this board to try out if this is something for me. But I can't seem to connect the board to my PC. Nothing happens in Windows when I connect it. The board lights "On" and the "L"-led blinks when I connect it, but nothing happens on the computer, there is nothing to see in the device manager. I have tried to install the CH340G driver, but as the board is not at all seen by the computer, this does no difference.

Is it a faulty board? I know I can't expect much for 3£, but I wanted to try it out. Is there something i missed, or is it simply a bad copy?

Yep. Just got another board today, with a 328p-pu and a 16u2-chip. It worked right away and was easily seen by windows. I guess my Visduino was just a bad copy. I will try to use it anyways using an external programmer or using the other board as programmer.

After getting burned by two official UNO boards (org vs cc)  I ordered some ebay Chinese boards via this way (from Peter) -->

Search on Ebay for : arduino uno r3
Select: buy it now
Sort for lowest price for item plus shipping.

I then looked at feedback and went through about 10 sellers until I found a 99% feedback.  It cost about $.50 US more than the cheapest, but I wanted to reward the seller.  It was the last UNO they had.

My suggestion - do not pick the worst seller - it just rewards them not to care about the buyers.  Spend a few cents and reward a better seller. 

Never will I buy an official board again!!   Probably for years I will not know if there will be more problems with it (drivers today - what tomorrow).  So ebay Chinese boards for me from now on.

First, I have this board, and I am making a similar board using the CH340G chip as for right now. This chip is much better than the ft232r which the nano is using: 1, price; 2, size (it's sop16 vs SSOP-28) the uno is using an even smaller usb-ttl. The only problem is the Chinese made CH340G chip. It's very well-known chip in China, while it's an unknown elsewhere. The other con about the trace is simply not true. The thinnest traces are 5mil and is more than enough to carry 40 mA which the pins can supply. and thinner traces are even a good idea. Think about it, if you are not smart, and hook up the pins incorrectly, then you will burn out the traces instead of the 328 chip. those thin traces are mini fuses for every pins!!! micro-USB is actually better than mini. most cell phone these days uses it. There are reason about it, and not all about size. Google about it.

My conclusion: it's not a perfect board, but it's at least twice better than the original, and I am loving it. and ignorance is not good.

The real con: pins are not aligned (see photo). Quality control is the last thing those Chinese sellers case about; if you are using this uno board with a shield, think twice before buying this cheap board.

The real real con: the design of this uno board is simply dumb. it's too large and too old. it will works, but it's not very artistic design in my point of view.

Last but not least. I got mine directly from the manufacturer, at least that is what they called themselves, for 2 dollars USD/ 12 RMB; Cheap as in price, the overall quality of the board is great! If I am going to make these in thousands, I probably can't buy all the component on the board with 2 USD. These people are working very hard to earn few cents from making these board. Calling it cheapest is simply inappropriate in my humble opinion.

Last word: when choosing the board, pick NANO instead of UNO, because the it's using the same 32pins IC as the NANO. The UNO uses a 28 pins dip package. The extra A6, A7 on this board is just extra from the 32pins IC; It will probably won't work if the bootloader is burned as an UNO; In that case, you need to burn the Nano bootloader to this board via the ISCP board in order to use those 2 extra analog pins;

I bought a VISduino but it's not showing on the serial port (COM) either. The red led ON is light and the green led L is blinking.

Hi guys, did you solve problem with programing of VIS duino Uno r3?
I have the win7 x64 with the new CH341 driver ver. 3.4.2014.8.
If I choose the board UNO, COM3 (correct for me), I have the message:
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x8c
Do I have to select the programmer? Which one? Or do something else?



Maybe the problem is with bootloader? If I follow the procedure from troubleshooting page and reset the board "The built-in L LED (which is connected to pin 13) should blink. If it doesn't, there may not be a bootloader on your board."   It doesn't blink.

The watchdog works, low is blinking.

Hi. If I choose the Leonardo instead of UNO it looks better. I haven't the red messages. ;)
