ESP32-MINI-1 and ESP32-MINI-1U are highly-integrated, small-sized Wi-Fi + Bluetooth + Bluetooth LE MCU modules that have a rich set of peripherals. The modules are ideal choices 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-1 comes with a on-board PCB antenna, and ESP32-MINI-1U with a connector for external antenna.
Both ESP32-MINI-1 and ESP32-MINI-1U have two variants:
• 85 °C version: integrating the ESP32-U4WDH chip
• 105 °C version: integrating the ESP32-U4WDH chip
In this datasheet unless otherwise stated, ESP32-MINI-1 refers to both ESP32-MINI-1-N4 and ESP32-MINI-1-H4, whereas ESP32-MINI-1U refers to both ESP32-MINI-1U-N4 and ESP32-MINI-1U-H4.
At the core of this module is ESP32-U4WDH*, an Xtensa 32-bit LX6 CPU that operates at up to 240 MHz. The user can power off the CPU and make use of the low-power co-processor 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.
