No issues at all ### ⭐⭐⭐⭐⭐ Seems to work with 3v (mostly) *by C***R on May 1, 2025* Seems to work with 3v logic level. Had some trouble with the inverse logic jumper. Looks like it floats and you need to use a pull-down resistor. When I did that 3v triggering stopped working though, so maybe the 5v rating refers to inverse logic mode? ## Frequently Bought Together - AEDIKO 4pcs DC 5V Relay Module - 1 Channel Relay Switch Board with Optocoupler Isolation, High or Low Level Trigger - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - BOJACK 3 Values 130 Pcs Solderless Breadboard 4 Pcs 830 Tie Points & 400 Tie Points & 126 Pcs Flexible Breadboard Jumper Wires --- ## 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.pl/products/345367150-4pcs-dc-5v-relay-module-1-channel-relay-switch-board](https://www.desertcart.pl/products/345367150-4pcs-dc-5v-relay-module-1-channel-relay-switch-board) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-29*
