Introduction

ESP32-SL is a general-purpose Wi-Fi+BT+BLE MCU module featuring an highly competitive form factor and ultra-low power consumption technology, with dimensions of only 18×25.5×2.18mm.

The ESP32-SL is widely applicable across various IoT scenarios, including home automation, industrial wireless control, baby monitors, wearable electronics, wireless location-aware devices, wireless positioning system signals, and other IoT applications, making it an ideal solution for IoT deployments.

At the core of this module is the ESP32-S0WD chip — a single-core member of the ESP32 family — featuring scalable and adaptive characteristics. Users can power down the CPU and leverage the low-power co-processor to continuously monitor peripheral status changes or whether analog values exceed defined thresholds. The ESP32-SL also integrates a rich set of peripherals, including capacitive touch sensors, Hall sensors, low-noise sensor amplifiers, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S, and I2C. The core processor ESP32 inside the ESP32-SL module features a built-in low-power Xtensa 32-bit LX6 MCU, supporting clock frequencies of 80 MHz and 160 MHz.

The ESP32-SL adopts an SMD package and supports rapid production via standard SMT equipment, providing customers with a highly reliable connectivity solution. It is particularly well-suited for automated, large-scale, and cost-efficient modern manufacturing, enabling convenient integration into a wide range of IoT hardware endpoints.
