I use this little board to power electronics that need to communicate with the ESP8266 at 3.3V if they are placed in another enclosure far apart or if the current requirements are too high. The PCB construction is sturdy and the form factor is small enough. The on-board LED gives good feedback so you know when the unit is on, but you may want to remove it if you're running off a battery and want to save power. ### ⭐⭐⭐⭐⭐ Analog DC modules *by on Reviewed in Australia 25 April 2024* Nice little step down modules for USB 5v to 3.3v DC ## Frequently Bought Together - HiLetgo 10pcs AMS1117-3.3 DC-DC Step-Down Power Module AMS1117-3.3V Buck Module LDO 800MA - HiLetgo 3pcs TP4056 Type-c USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions - 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 --- ## 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.pt/products/347655478-hiletgo-10pcs-ams1117-3-3-dc-dc-step-down-power](https://www.desertcart.pt/products/347655478-hiletgo-10pcs-ams1117-3-3-dc-dc-step-down-power) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-28*
