The processor runs an RTOS and the TCP\/IP stack, handling all Wi-Fi connection management and data transfer. In AT command mode, an external MCU sends serial AT commands to configure Wi-Fi and send\/receive data. In standalone mode, the ESP8266 runs user firmware directly (Arduino, NodeMCU, MicroPython). The onboard PCB antenna radiates at 2.4 GHz. The 1 MB SPI Flash stores firmware and user data. The CH_PD pin must be held HIGH for normal operation, and GPIO0 must be LOW during programming mode.","pin_description":"\n
