ESP32-WROOM-32D 32MBit (4MB) module

Description

ESP32-WROOM-32D is a powerful MCU module that combines Wi-Fi and Bluetooth (BR/EDR + BLE) technologies. It can work with a frequency of 240 MHz (two cores) and has a built-in 448 KB of ROM, 520 KB of SRAM and 4 MB of SPI Flash memory. It offers the user a rich set of digital buses including UART, SPI, SDIO, I2C, PWM, I2S, IR, GPIO, capacitive touch sensor, ADC and DAC. It also has a built-in PCB antenna. It is designed for a wide variety of applications, from sensor networks to the most demanding tasks such as voice encoding, music streaming, and MP3 decoding. The module has a built-in PCB antenna.
