Got this one with external antenna and it worked!Easy replacement on the sensor-collecting circuit (same dimensions, drop-in replacement), but keep in mind that to use the external antenna you must rotate a TINY soldered resistor (or just remove it and bridge the other contacts)In my signal strength tests, the external antenna had 10-20 dBs improvement (in my shed I got average -75dB).Be aware of antenna position, and make sure to test signal strength in your application to determine the best orientation (I was surprised that in my case the second-floor router had better connection). ### ⭐⭐⭐⭐ Not the best price. *by on Reviewed in the United States April 26, 2023* Board works decently but it's about 4 times the price then if you were buying on alibaba ### ⭐ Board resets continually *by on Reviewed in the United States March 4, 2023* I was able to download several different programs to the board, but all of them crash after a few seconds with a watchdog timer reset. I have several other similar boards that work correctly. I will return this defective board. --- ## 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.sk/products/373859067-mayata-wemos-d1-mini-pro-4mb-16mb-external-antenna-connector](https://www.desertcart.sk/products/373859067-mayata-wemos-d1-mini-pro-4mb-16mb-external-antenna-connector) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-25*
