ESP Prog V1.0 USB To ESP8266 Programmer - CH340C With Auto-Download Circuit

About This Product

ESP8266 tinkerers and IoT developers, this USB programmer makes working with ESP-01 and ESP-01S modules so much easier! The CH340C chip provides reliable USB-to-serial communication, and the built-in auto-download circuit means you don't have to manually press buttons to put your module into programming mode - it handles that automatically when you start a upload. The blue version includes a reset button for when you need manual control, and it has both male and female pins, making it super versatile for different connection scenarios. It works seamlessly with Arduino IDE (just select 'Generic ESP8285 Module' as your board), Ai-thinker ESP8266 Flasher, and Espressif's official FLASH_DOWNLOAD_TOOLS. The compact design measures about 1.97x0.55 inches, so it doesn't take up much space on your workbench. I've used this with both the original ESP-01 and the newer ESP-01S modules (which have 4MB flash and improved WiFi performance), and it programs both flawlessly. The auto-download feature is what really sets this apart - no more fiddling with GPIO pins or timing button presses during programming. It's compatible with the 4MB flash versions that have stronger signals and better performance. Whether you're building IoT devices, WiFi controllers, or just learning ESP8266 programming, this little programmer eliminates so much of the frustration that comes with getting code onto these tiny modules. Definitely a must-have tool if you're serious about ESP8266 development!
