2-Pack LED Matrix, 16x16 Ws2812b Led Matrix Panel, Flexible Addressable RGB Pixels LED Display Work with Arduino/Raspberry Pi for Indoor DIY Projects

Very good brightness. Adding a diffuser helps smooth out the look.I paid more per/pixel compared to a roll, but I didn't have to spend time cutting/soldering rows together to build a matrix. Attached connectors made it easy to connect multiple modules together and each has a separate pair of power wires for injecting power at every module.I used the FastLED_NeoMatrix library with an Arduino to drive them. The library makes it easy to string multiple matrix modules together and treat the whole thing like a simple two dimensional array.

I ordered a few of these to experiment with WLED and ESP32 projects. These LEDs have been working great, and I’ve had no issues so far.

I was very surprised by the color range of these panels since they were on the cheaper side, but they are quite good. A more expensive brand I've tried was less accurate than this one, which would make some of the designs I made look very off. This brand is just way better.

Works pe4fect with simhub for flags and gears..

I like the price of the product. I also like how you have the option to connect multiples of them together. When I was testing mine it all worked for the first 20 minutes of testing different brightness levels and colors. Its flexible like they advertise. The only issue I have so far is a single LED stays on and green when I power it. It's very dim, but noticeable. I disconnected the datain wire to see if it's a data issue or a power issue and I confirmed that it's a power issue. For some reason that one LED is HIGH and dim. I will return this one and get a new one, so that's a little inconvenient, but I figure it's just an isolated incident. I attached photos of it working and with the stray LED.
