This has to be the easiest way to program an ESP-01. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works great. *by M***Y on Reviewed in the United States on April 23, 2024* I thought I would have to wire an external jumper to get the upload to work, but after reading one other review where they had the settings necessary to auto-upload, I found out it works without having to have a switch or jumper. In the Arduino IDE, the flash mode must be "Dout" and reset method "dtr nodemcu".It is nice having the reset switch, restart the code while watching the serial monitor. It is also very convenient having the extra pin header for wiring jumpers to a breadboard while being powered by the USB port. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars One and only for Tasmota *by Y***K on Reviewed in the United States on September 25, 2024* This is the one for me.Nothing worked other than this module.All my ESP01s programed flawlessly.Thank you ! --- ## 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.sk/products/243618791-2pcs-usb-to-esp8266-breakout-ch340c-esp-01-esp-01s](https://www.desertcart.sk/products/243618791-2pcs-usb-to-esp8266-breakout-ch340c-esp-01-esp-01s) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-29*
