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. The ordering information for ESP32-MINI-1 and ESP32-MINI-1U is listed as follows: Table 1: Ordering Information Module Ordering code Chip embedded Module dimensions (mm) ESP32-MINI-1 (85 °C version) ESP32-MINI-1 (105 °C version) ESP32-MINI-1-N4 ESP32-MINI-1-H4 ESP32-U4WDH ESP32-U4WDH 13.2 × 19.0 × 2.4 ESP32-MINI-1U (85 °C version) ESP32-MINI-1U-N4 ESP32-U4WDH ESP32-MINI-1U (105 °C version) ESP32-MINI-1U-H4 ESP32-U4WDH 13.2 × 13.5 × 2.4 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. For more information on ESP32 chips, please refer to ESP32 Series Datasheet. 1.3 Applications • Generic Low-power IoT Sensor Hub • Generic Low-power IoT Data Loggers • Cameras for Video Streaming • Over-the-top (OTT) Devices • Speech Recognition • Image Recognition • Mesh Network • Home Automation • Smart Building • Industrial Automation • Smart Agriculture • Audio Applications • Health Care Applications • Wi-Fi-enabled Toys • Wearable Electronics • Retail & Catering Applications Espressif Systems 3 Submit Documentation Feedback ESP32-MINI-1 & MINI-1U Datasheet v1.1 Contents Contents 1 Module Overview 2 1.1 Features 2 1.2 Description 3 1.3 Applications 3 2 Block Diagram 8 3 Pin Definitions 9 3.1 Pin Layout 9 3.2 Pin Description 10 3.3 Strapping Pins 12 4 Electrical Characteristics 14 4.1 Absolute Maximum Ratings 14 4.2 Recommended Operating Conditions 14 4.3 DC Characteristics (3.3 V, 25 °C) 14 4.4 Current Consumption Characteristics 15 4.5 Wi-Fi RF Characteristics 16 4.5.1 Wi-Fi RF Standards 16 4.5.2 Transmitter Characteristics 16 4.5.3 Receiver Characteristics 17 4.6 Bluetooth Radio 18 4.6.1 Receiver – Basic Data Rate 18 4.6.2 Transmitter – Basic Data Rate 19 4.6.3 Receiver – Enhanced Data R.
