ESP32 Development board

Features

• Main Processor: Tensilica Xtensa 32-bit LX6microprocessor

  • Cores: 2 or 1 (depending onvariation)

    All chips in the ESP32 series are dual-core except forESP32-S0WD, which is single-core.

  • ClockFrequency: up to 240 MHz

  • Performance: up to 600 DMIPS

• Wireless Connectivity

  • Wi-Fi: 802.11 b/g/n/e/i (802.11n @ 2.4 GHz up to 150 Mbit/s)
  • Bluetooth: v4.2 BR/EDR and Bluetooth Low Energy(BLE)

• Low Power: Low power optionsutilize the ULP co-processor to ensure that you can still do ADCconversions, computation, and level thresholds while in deep sleep.

• Memory

  • Internal Memory

    • ROM: 448 KiB

      For booting and corefunctions.

    • SRAM: 520 KiB

      For dataand instruction.

    • RTC Slow SRAM: 8 KiB

      For co-processor accessing during the deep-sleep mode.

    • RTC Fast SRAM: 8 KiB

      For data storage andmain CPU during RTC Boot from the deep-sleep mode.

    • eFuse: 1 Kibit

      Of which 256 bits are usedfor the system (MAC address and chip configuration) and the remaining 768 bitsare reserved for customer applications, including Flash-Encryption and Chip-ID.

    • Embedded Flash: 0 MiB or 2 MiB(depending on variation)

      ESP32-D2WD has 2 MiB of embedded flash, internallyconnected via GPIO16, GPIO17, SD_CMD, SD_CLK, SD_DATA_0, and SD_DATA_1. Theother chips in the ESP32 series have no embedded flash.

  • External Flash and SRAM: ESP32 without embeddedflash supports up to 4 × 16 MiB of external QSPI flash and 8 MiB SRAM withhardware encryption based on AES to protect developer s programs and data.

    ESP32 chips with embedded flash do not support the address mapping betweenexternal flash and peripherals.

• PeripheralInput/Output: Rich peripheral interface with DMA that includescapacitive touch, ADCs (analog-to-digital converter), DACs (digital-to-analogconverter), I²C (Inter-Integrated Circuit), UART (universal asynchronousreceiver/transmitter), CAN 2.0 (Controller Area Network), SPI (SerialPeripheral Interface), I²S (Integrated Inter-IC Sound), RMII (Reduced Media-Independent Interface), PWM (pulse width modulation), and more.

• Security

  • IEEE 802.11 standard security featuresall supported, including WFA, WPA/WPA2, and WAPI
  • Secure boot
  • Flash encryption
  • 1024-bit OTP, up to 768-bit for customers
  • Cryptographic hardware acceleration: AES, SHA-2, RSA, elliptic curvecryptography (ECC), random number generator (RNG)
