The ESP32 WROOM 32D Module Authentic Quality is an original, industrial-grade wireless microcontroller module manufactured by Espressif Systems. 3.0V to 3.6V DC (3.3V nominal).
The ESP32 WROOM 32D Module Authentic Quality is an original, industrial-grade wireless microcontroller module manufactured by Espressif Systems. Upgraded from the classic ESP-WROOM-32, the "32D" variant incorporates an optimized ESP32-D0WD SoC layout that delivers improved RF performance and signal stability. Powered by a 32-bit Xtensa dual-core LX6 processor running at up to 240 MHz, it is designed for demanding IoT applications, smart home gateways, wireless video/audio streaming, and industrial automation.
The module integrates 4MB (32Mbit) of high-speed SPI Flash memory alongside 520KB internal SRAM, 448KB ROM, and 16KB RTC SRAM. For wireless communications, it supports 2.4 GHz Wi-Fi (802.11b/g/n) and dual-mode Bluetooth (Classic BR/EDR and Bluetooth Low Energy v4.2). It features a redesigned, highly efficient onboard MIFA PCB trace antenna for superior wireless range and reliability.
Designed for direct surface-mounting (SMD) on custom PCBs via castellated solder pads, the ESP32-WROOM-32D exposes up to 32 programmable GPIO pins supporting hardware UART, SPI, I2C, I2S, PWM, ADC, DAC, TWAI (CAN 2.0), and capacitive touch sensing. Operating on 3.0V to 3.6V DC logic power with multiple ultra-low-power sleep modes, it is a versatile processing engine for custom production electronics.
