ESP-01S ESP8266 Wireless Transceiver Module

Already flashed with the latest Tasmota firmware.

The ESP-01S is a small and powerful WiFi module that allows you to easily integrate your projects into your WiFi network.

The built-in serial interface allows you to program your own IoT projects. Or you can use the numerous example libraries you can find on the Internet.

Bring your projects online. The module can be used very well with Arduino, Raspberry Pi, Tasmota, or many other projects.


Differences between ESP-01 and ESP-01S

The red power LED has been removed - this means the ES-01S has lower consumption

The blue LED is connected to GPIO2 (Active Low) instead of TX

Inputs EN, RST and GPI0 have a pull-up resistor (12 kOhm) and are Set to 3.3 V

New firmware is already preinstalled. With the QIO SPI mode activated, up to 80% higher transmission speed is achieved


ATTENTION: The module and the IOs must be operated with 3.3V.

Operation with 5V voltage damages the module!
