Introduction of ESP32S NodeMCU Development Board

ESP32S NodeMCU Development Board created by Nodee MCU to evaluate the ESP-WROOM-32 module. It has an ESP32 microcontroller. It Boats Wifi, Bluetooth, Ethernet and Low Power Support all In a Single-chip.


Flash Layout:

ESP32 module has an internal flash organized in a single flash. And also contain pages of 4096 bytes each. The start address of the flash is 0x00000. Many areas of flash addresses are reserved for ESP32 IDF SDK and Zerynth VM. There are two different layouts based on the presence of BLE support ESP32S NodeMCU Board price is also effective.
