Introduction

ESP32-MINI-1 and ESP32-MINI-1U are general-purpose Wi-Fi + Bluetooth + BLE MCU modules with powerful performance and rich peripheral interfaces, suitable for a wide range of IoT applications such as smart home, consumer electronics, and industrial control. Both modules feature extremely high integration and a compact form factor, making them especially well-suited for space-constrained applications such as bulb lamps, switches, and sockets. ESP32-MINI-1 uses a PCB on-board antenna, while ESP32-MINI-1U connects to an external antenna via a connector. Both modules come in two variants: an 85°C variant integrating the ESP32-U4WDH chip and a 105°C variant integrating the ESP32-U4WDH chip. The two variants differ only in their operating temperature range. The ESP32-U4WDH chip is equipped with 4MB embedded flash, belongs to the ESP32 series, and features an Xtensa 32-bit dual-core processor supporting clock frequencies of up to 240MHz. Users can power down the CPU and use the low-power coprocessor to monitor peripheral status changes or detect when certain analog values exceed a threshold. The ESP32 series integrates a rich set of peripherals, including capacitive touch sensors, SD card interface, Ethernet interface, high-speed SPI, UART, I2S, and I2C.
