The ESP32-WROOM-32D-N8 is a powerful Wi-Fi, Bluetooth, and Bluetooth Low Energy (BLE) module manufactured by Espressif Systems, featuring an integrated 8 MB SPI flash memory variant of the standard 32D design.
Key Specifications:-
• Core: Dual-core Xtensa 32-bit LX6 microprocessor, adjustable from 80 MHz to 240 MHz.
• Memory: 8 MB SPI flash, 520 KB SRAM, and 448 KB ROM.
• Wireless: Wi-Fi 802.11 b/g/n (up to 150 Mbps) and Bluetooth v4.2 BR/EDR + BLE.
• Antenna: On-board PCB antenna (unlike the 32U model which uses a UFL connector).
• Operating Voltage: 3.0 V to 3.6 V (Typical 3.3 V).
• Operating Temperature: -40 °C to +85 °C.
• Lifecycle Status: Classified by Espressif as NRND (Not Recommended for New Designs), meaning new projects should ideally transition to newer series like the ESP32-S3.
Common Uses:-
• Internet of Things (IoT) sensor hubs and data loggers
• Home automation and smart control panels
• Wearable electronics and low-power battery-operated devices
