ESP-01S ESP8266 Wireless Transceiver module
Already flashed with the latest Tasmota firmware.
The ESP-01S is a small and powerful WiFi module with which you can easily integrate your projects into your WLAN network.
The built -in serial interface allows you to program your own IoT projects. Or you use the numerous sample libraries that 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 was removed - this has the ES -01S a lower consumption
The blue LED is connected to GPIO2 (Active Low) instead of TX
Inputs, RST and GPI0 have a pull-up resistance (12 kohm) and are set to 3.3 V
New firmware is already pre -installed. The activated QIO SPI mode achieves up to 80 % higher transmission speed
Attention: The module and the iOS must be operated with 3.3V.
A operation with 5V voltage damages the module!
