To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
DO NOT BUY!!!!!! When powered by external 9v source, it doesn't regulate to 5v and therefore sent 9v straight to the USB port destroying the CPU on the MAC. A $550 repair to replace the mac book logic board and CPU. Crap Chinese product -avoid at all costs!!
UPDATE3: Elegoo customer support are superb. My board is now working, they sent out a replacement super quick, and this one showed up in Device Manager correctly the first time I plugged it in. Really happy to actually to be able to work on some projects now. 4 stars because I never trust 5 star reviews, and the fact that I did have to send the board back.
ORIG: It arrived, packaged pine, but it was not recognised by Win7 when I connected via USB. I did some googling and it seems the bootloader is not loaded to the arduino. The only way to load the bootloader is via another working arduino. So I will return this one.
UPDATE: I just ordered a second (how stupid am I), the second one also does not work! I noticed the first board looked like it had the official USB controller chip (QU18 or something), but this one had something different (a1shr and another chip has AMS1175.0 Q1818). I will return the second one - I won't buy another. This board is probably good if you are already an expert with Arduino's and can load a bootloader to it (you need another working arduino to do that I believe).
UPDATE2 (same day to update 1): So - I got it working. Download Arduino IDE and save to desktop. Go to Device Manager, Right Click on Unidentified Device, Update Drivers, browse to the Driver sfolder of the Arduino download (I downloaded the zip and saved to program files), then let windows do it's thing (I didn't specifiy any particular folder, just pointed it at 'drivers' in that arduino folder I downloaded from the official site), then it worked. Device shows up as arduino, and the IDE blink test works (note the LED was blinking all the time anyway, so I changed the blinktest value to 10seconds, 10000 so i knew it had uploaded). Now to have some fun!
Would give 5 stars but the USB cable was not functional on my PC, being it is the old style USB cable, was hard for me to find one. Once I tested with a replacement cable the elegoo uno r3 works perfectly, proving the faulty or somehow incompatible cable. I thought it was DOA. Many would have returned item plugged in no signs of life.
Excellent. Just the job to upgrade the Firmware on the 3D printer. Looks to be good quality, very well soldered base. Did have to Buy some connecters to connect to the motherboard. Comes with No instructions. Overall Value for the Money.
The board looks great and was running perfectly with my project. However, I recently have an uploading problem. It is actually showing an error message with incompatibility when I try to upload the same code that used to upload. What can I do ?
