Overview
The schtoeta ESP32 WROOM MCU Module - 16MB (PCB Antenna) is a wireless MCU module based on the ESP32-D0WDQ6. It combines 2 CPU cores, an adjustable CPU clock frequency from 80 MHz to 240 MHz, and 16 MB flash memory in a compact module format. The integrated PCB antenna supports wireless connectivity in a space-efficient design.
This module supports Wi‑Fi, Bluetooth, and Bluetooth LE, and reaches a maximum data rate of 150 Mbps. It also specifies an RF output power of 20 dBm and a sleep current of 5 µA. Operating system support includes freeRTOS with LwIP, and TLS 1.2 with hardware acceleration is supported for secure connectivity.
With interfaces including SD card, Ethernet, SPI, UART, I2S, and I2C, this module is suitable for embedded designs that require wireless communication and standard peripheral connectivity.
