Ordered this one, it shipped fast, plugged it in, flashed it, and it works fine. As others have said you have to move the antenna resistor, but that's not hard. I kinda think they should ship with the resistor solder to the external antenna, cause if you didn't want to use the external why not just order a regular d1mini. But overall I'm happy. Review: Works great - If you are going to use the external antenna instead of the onboard ceramic antenna, you need to remove the zero-ohm resistor next to the antenna connector, and solder bridge as shown by the red arrow. Otherwise, the external antenna isn't connected. Once done, everything works great. ## Features - Based on ESP8266 ESP-8266EX CP2104 - Compatible with Arduin, use Arduino IDE for programming - 11XI/O pin, 1XADC pin (input 0-3.3V), support OTA online, onboard 5V 1A switching power supply (large input 24V) - Lange weibliche pins x2pcs,Kurze weibliche pins x2pcs,Normal pins x2pcs,WeMos D1 mini Pro x1pcs - 32MBIT=4MB,128MBIT=16MB,esp8266 series wireless antenna x1pcs ## Images ![Mayata WEMOS D1 Mini Pro 4MB/16MB External Antenna Connector NodeMCU Based esp8266 Series Antenna ESP-8266EX CP2104 Development Board (Development Board + Antenna 128MBIT=16MB) - Image 1](https://m.media-amazon.com/images/I/51qf-E6FuIL.jpg) ![Mayata WEMOS D1 Mini Pro 4MB/16MB External Antenna Connector NodeMCU Based esp8266 Series Antenna ESP-8266EX CP2104 Development Board (Development Board + Antenna 128MBIT=16MB) - Image 2](https://m.media-amazon.com/images/I/61dM6Hy2uEL.jpg) ![Mayata WEMOS D1 Mini Pro 4MB/16MB External Antenna Connector NodeMCU Based esp8266 Series Antenna ESP-8266EX CP2104 Development Board (Development Board + Antenna 128MBIT=16MB) - Image 3](https://m.media-amazon.com/images/I/71A7grtgNBL.jpg) ![Mayata WEMOS D1 Mini Pro 4MB/16MB External Antenna Connector NodeMCU Based esp8266 Series Antenna ESP-8266EX CP2104 Development Board (Development Board + Antenna 128MBIT=16MB) - Image 4](https://m.media-amazon.com/images/I/710Gvd0h6-L.jpg) ![Mayata WEMOS D1 Mini Pro 4MB/16MB External Antenna Connector NodeMCU Based esp8266 Series Antenna ESP-8266EX CP2104 Development Board (Development Board + Antenna 128MBIT=16MB) - Image 5](https://m.media-amazon.com/images/I/518wOcQtcxL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works lol *by J***N on April 30, 2022* I had ordered 3 d1mini pros from another company, they wouldn't communicate with my computer, but they were also on 20 for 3. Ordered this one, it shipped fast, plugged it in, flashed it, and it works fine. As others have said you have to move the antenna resistor, but that's not hard. I kinda think they should ship with the resistor solder to the external antenna, cause if you didn't want to use the external why not just order a regular d1mini. But overall I'm happy. ### ⭐⭐⭐⭐⭐ Works great *by M***A on July 2, 2019* If you are going to use the external antenna instead of the onboard ceramic antenna, you need to remove the zero-ohm resistor next to the antenna connector, and solder bridge as shown by the red arrow. Otherwise, the external antenna isn't connected. Once done, everything works great. ### ⭐ DOA *by A***A on November 5, 2022* Wanted to simply load code from a D1 mini from a previous project, but wasted time on this. It loaded code, but would not run. This code is running on other D1 mini modules. Chip got hot. Appears to be bad hardware. Returning. Side note. This device does not have a diode to avoid 5V back feeding to the USB. This is populated with a 0R resistor. Probably not important in most applications, but the pictures do not match what you get. As others noted, the 0R for the antenna selection is setup for using the ceramic. The module does not have FCC approval and is not meant for commercial use. --- ## 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/90254730-mayata-wemos-d1-mini-pro-4mb-16mb-external-antenna-connector](https://www.desertcart.sk/products/90254730-mayata-wemos-d1-mini-pro-4mb-16mb-external-antenna-connector) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-15*
