USB Serial Programmer with CH340 and ESP-01S Board

It is a must have tool for developers, hobbyists, and electronics enthusiasts. With seamless compatibility across all platforms and a user-friendly interface, you’ll be able to program your devices effortlessly.

This module is a USB adapter/ programmer and comes with an ESP-01S wifi board
It is conveniently fitted with a 2x4P 2.54mm female header to plug the ESP-01 /ESP-01S
The module is based on the USB-UART bridget CH340 from WCH which is compatible with all platforms.
Note: For an usage with ESP8266 platform and IDE, it is necessary to switch manually the GPIO0 state for working mode, in order to get a fully automatic upload it is most likely possible, for a very limited effort, to assign an unused control line from CH340 to driver the GPIO0 line (probably at the cost of a necessary logic inversion).

Size: 48 x 17 x 12 mm

Package includes:
1x USB ADAPTER Programmer

1x ESP-01S

Charlotte ★★★★★ Oct 17, 2026

The auto-reset circuit works perfectly with my ESP-01S, and the CH340 driver was recognized instantly on Windows 10 without any extra steps.

Carter ★★★★★ Oct 13, 2026

Plugged it straight into my Linux box and it showed up as a serial port with zero driver hunting, which honestly surprised me for the price. The CH340 chip handles both 3.3V and 5V so I stopped worrying about frying the ESP-01S while flashing. Flashed three modules back to back without a single fail

Andrew ★★★★★ Oct 12, 2026

The little jumper lets you switch between programming and run mode without rewiring, which saved me a ton of fiddling on my bench. It's just a bare CH340 board with the ESP-01S socket, but it flashed my modules on the first try and the pins lined up cleanly.
