Crowtail – ESP8266 NodeMCU 2.0 is a universal WiFi module for IoT projects with a ready Crowtail interface, microUSB port, and Li-Po battery charging function. It works well in mobile and stationary applications based on Arduino IDE or NodeMCU Lua.
Description
Crowtail – ESP8266 NodeMCU 2.0 is a development module for IoT projects, based on the ESP8266 chip with an 80 MHz clock speed and 4 MB Flash memory. Equipped with six Crowtail connectors, it allows direct connection of compatible modules without the need for additional converters. The board integrates a CP2104 USB–UART converter with automatic reset support, simplifying the code uploading process. Additionally, a socket for a 3.7 V Li-Po battery and a charging circuit with a status LED are provided. The module also operates without a battery, powered via microUSB, with automatic power switching. It is compatible with the Arduino IDE and the NodeMCU environment (the module includes a Lua interpreter by default).
