Product Description

Warning! This is the bare ESP32 IC! Click here for the usable module. No returns if you order this by accident. 

Bare ESP32 from Tronixlabs Australia. Ideal for making your own ESP32-based solution.

This is the dual-core QFN 6x6 model without embedded flash. 


  • Main Processor: Tensilica Xtensa 32-bit LX6 microprocessor
    • Cores: 2 or 1 (depending on variation)
      All chips in the ESP32 series are dual-core except for ESP32-S0WD, which is single-core.
    • Clock Frequency: 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 options utilize the ULP co-processor to ensure that you can still do ADC conversions, computation, and level thresholds while in deep sleep.
  • Internal Memory
    • ROM: 448 KiB – For booting and core functions.
    • SRAM: 520 KiB – For data and instruction.
    • RCT SLOW SRAM: 8 KiB – For co-processor accessing during deep-sleep mode.
    • RCT FAST SRAM: 8 KiB – For data storage and main CPU during RTC Boot from the deep-sleep mode.
    • EFUSE: 1 Kibit – Of which 256 bits are used for the system (MAC address and chip configuration) and the remaining 768 bits are 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, internally connected via GPIO16, GPIO17, SD_CMD, SD_CLK, SD_DATA_0 and SD_DATA_1. The other chips in the ESP32 series have no embedded flash.
  • External Flash and SRAM: ESP32 without embedded flash supports up to 4 × 16 mebibytes of external QSPI flash and SRAM with hardware encryption based on AES to protect developer’s programs and data.
  • Peripheral Input/Output: Rich peripheral interface with DMA that includes capacitive touch, ADCs (analog-to-digital converter), DACs (digital-to-analog converter), I²C (Inter-Integrated Circuit), UART (universal asynchronous receiver/transmitter), CAN 2.0 (Controller Area Network), SPI (Serial Peripheral Interface), I²S (Integrated Inter-IC Sound), RMII (Reduced Media-Independent Interface), PWM (pulse width modulation), and more.
  • Security
    • IEEE 802.11 standard security features all 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 curve cryptography (ECC), random number generator (RNG)
