Description

The ESP32-MINI-1 is a versatile Wi-Fi + Bluetooth + Bluetooth LE MCU module with powerful features and a wide range of peripheral interfaces, suitable for various IoT application scenarios such as smart homes, smart buildings, consumer electronics, and industrial control. The module is designed to be compact and small in size, making it especially ideal for applications with limited space, such as light bulbs, switches, and sockets.

The module comes in two variants:

  • 85°C version
  • 105°C version

Both variants feature a PCB onboard antenna and are equipped with a 4MB SPI flash. The information provided in this document applies to both types of modules.
