(Switching lights)Also remember the relays are good for switching a maximum of 440Watts at 220V.So don't go switching your kettle or microwave as it will burn out!Overall I would definitely buy another one. ### ⭐⭐⭐⭐⭐ Works fantastically, but make sure you get a schematic *by on Reviewed in the United Kingdom 28 May 2013* You look at a board and assume it works one way... and then you get a loud snap and a cloud of magic smoke. Always read the schematic. Other than that, works brilliantly (I bought a second one after realising my mistake). Well put together bit of kit and at a great price. ### ⭐⭐⭐⭐⭐ Great for AC power *by on Reviewed in the United Kingdom 3 November 2017* Great but remember that these are only good for AC power (e.g. mains) and no good for 12V DC for example --- ## 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.be/products/51592266-sainsmart-8-channel-solid-state-relay-board-for-arduino-uno](https://www.desertcart.be/products/51592266-sainsmart-8-channel-solid-state-relay-board-for-arduino-uno) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-24*
