1.2 Description
ESP32-MINI-1U is a highly-integrated, small-sized Wi-Fi + Bluetooth + Bluetooth LE MCU module that has a
rich set of peripherals. This module is an ideal choice for a wide variety of IoT applications, ranging from home
automation, smart building, consumer electronics to industrial control, especially suitable for applications within a
compact space, such as bulbs, switches and sockets.
ESP32-MINI-1U is an SMD module, with 4 MB SPI flash and a U.FL to connect with an external IPEX antenna.
At the core of this module is ESP32-U4WDH*, an Xtensa 32-bit LX6 CPU that operates at up to 160 MHz. The
user can power off the CPU and make use of the low-power coprocessor to constantly monitor the peripherals for
changes or exceeding of thresholds.
This ESP32 chip integrates a rich set of peripherals, ranging from capacitive touch sensor, Hall sensor, SD card
interface, Ethernet, high-speed SPI, UART, I2S, I2C, etc.
