Review on 🔴 Large Size P10 Red LED Panel Display - 32cm X 16cm - 512 pcs of LED - Individually Addressable - Controlled by Uno R3 with Arduino IDE by Tonya Washington

PRO I found the setup process to be easy to complete using the information on the seller's website as well as the card that came with the unit. Arduino libraries and sketches are provided. The vendor worked smoothly and was a good starting point for developing your own messaging application. Everything was well packaged and all the cables, connectors etc needed to work with the Arduino are included. bright red light and as you can see in my video they are clearly visible from 60-70 feet away. If you mount the panel(s) in a small frame/box with, as another reviewer mentioned, some sort of transparent diffuser, I think this display will stand out; although it's great the way it is. The brightness is controlled by simply adjusting the auxiliary voltage from 3 to 5 volts DC. A panel can be controlled quite well directly from the Arduino. In my testing, the panel drew nearly an amp from an external/auxiliary power supply at 5 volts. Obviously it doesn't come close to that just being powered by the Arduino. This monochrome red P10 panel was priced very cheaply. The panel looks very well made and very solid! And the form factor is just right to create a larger display by combining several of these blocks. Ports on the back of the device and vendor-supplied software make this easy. As already mentioned, the connections and pins are very well marked on the back of the device. Disadvantages Nothing to talk about. Of course, a similar device with RGB LEDs would be nice, but then it wouldn't be in the price range of this model. Perhaps my biggest disappointment is that just prior to writing this review I checked the Revain storefront and found that the product is CURRENTLY NOT AVAILABLE and there is no indication if or when this will be the case. Pity! Perhaps you can look elsewhere, or hopefully it will be available again from Revain soon.
