The programmer worked great out of the box, and has continued to function properly over time. Slide the switch to the left to view serial communications. Slide the switch to the right and program the ESP-01 with ease. This is so much better than using a FTDI and jumper cables while also grounding the pin to upload new code. I should probably note my picture includes an ESP-01, not included with the programmer. ### ⭐⭐⭐⭐⭐ What a life saver *by E***N on Reviewed in the United States on 26 January 2021* Building a little breadboard programmer is fun the first time, but then when the cat gets it, it's less fun the second time. The ESP01's are a little more annoying to setup than the bigger siblings.I think it's worth building a basic one yourself, as a learning experience, then quickly move on to this.These ESP01's are so cheap and useful, it's easy to grab a bunch then setup for a single sensor and plant them all over the house. Doing that requires a reliable and easy way to program and test. I had tons of problems with a loose wire in the breadboard, or any number of things which made this frustrating. This little gadget makes a workflow for programming and testing so much more reliable.I have no issues with this in a USB3 port which puts out 5v. ### ⭐⭐⭐⭐⭐ Parfait *by R***E on Reviewed in France on 28 January 2023* Bonjour,Adaptateur parfait pour la programmation des esp01 avec visualstudio code --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/269736415-stemedu-2pcs-usb-to-esp-01-adapter-esp8266-wireless-wifi](https://www.desertcart.pl/products/269736415-stemedu-2pcs-usb-to-esp-01-adapter-esp8266-wireless-wifi) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-15*
