The SD card was supposedly flashed with NOOBS for a simple OS installation, but with mine it was corrupted and I just got a screen showing a colorful rainbow. Took me an hour to download and install the Raspbian OS...which kinda defeats the purpose of spending $30 to get a preloaded card. Maybe others experiences are different but for me this kit wasn't plug n play. ### ⭐⭐ Not Worth It. Unresponsive. *by A***M on Reviewed in the United States on February 13, 2017* The kit was packaged very nicely. But, I bought the kit hoping for a plug and play solution. The SD card didn't work, I needed to format it and install NOOBS myself. I emailed the seller and never heard back.In the end, it was more of a pain than it was worth. ### ⭐⭐⭐⭐⭐ Great quality for a great price! *by J***S on Reviewed in the United States on February 2, 2017* This was a great purchase! I couldn't be happier with the quality of the product! Having noobs preloaded made this a cinch to use as well! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/35769412-longruner-cnc-shield-expansion-board-v3-0-board-a4988-stepper](https://www.desertcart.fr/products/35769412-longruner-cnc-shield-expansion-board-v3-0-board-a4988-stepper) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-23*
