ESP32 WiFi/Bluetooth Dev Board ESP-32S ESP-WROOM-32 1pc/5pcs/10pcs

Specifications

• The core of this module is ESP32-D0WDQ6 chip, with scalable, adaptive features.
• Two CPU cores can be individually controlled or powered on.
• The clock frequency is adjustable from 80 MHz to 240 MHz.
• The user can cut off the power of the CPU and use the low-power coprocessor to continuously monitor the status of the peripherals or whether some of the analog values ​​exceed the threshold.

CPU and Memory

The ESP32-D0WDQ6 has two low-power Xtensa® 32-bit LX6 MCUs. On-chip storage includes:

• 448 KB ROM for program startup and kernel function calls.
• 520 KB on-chip SRAM for data and instruction storage.
• 8-KB SRAM in RTC, or RTC Slow Memory, can be accessed by the co-processor in deep-sleep mode.
• 8-KB SRAM in RTC, RTC Fast Memory, which can be used for data storage and access by the host CPU when RTC starts in deep-sleep mode.
• 1 kbit eFuse, where 256 bits are system-specific (MAC address and chip set); the remaining 768 bits are reserved for user applications, including Flash encryption and chip ID.
• ESP-WROOM-32 integrates 4MB of SPI Flash
