About this product
A NodeMCU-style development board built around the Espressif ESP8266 Wi-Fi SoC with a CP2102 USB-to-UART bridge for flashing and serial output. It supports 2.4 GHz 802.11 b/g/n Wi-Fi, runs on 3.3 V logic, and exposes GPIO, serial, SPI, I2C-capable, PWM, and ADC functions. Module revision, flash capacity, and pinout vary between NodeMCU-compatible layouts and should be verified on the received board.
