ESP32-SL specification V1.0

1.PRODUCT OVERVIEW

ESP32-SL is a general-purpose Wi-Fi+BT+BLE MCU module, with the industry's most

competitive package size and ultra-low energy consumption technology, the size is

only 18*25.5*2.8mm.

ESP32-SL can be widely used in various IoT occasions, suitable for home automation,

industrial wireless control, baby monitors, wearable electronic products, wireless

position sensing devices, wireless positioning system signals, and other IoT

applications. It is an IoT application Ideal solution.

The core of this module is the ESP32-S0WD chip, which is scalable and adaptive. The

user can cut off the power of the CPU and use the low power consumption to assist the

processor to continuously monitor the status changes of peripherals or whether certain

analog quantities exceed the threshold. ESP32-SL also integrates a wealth 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 ESP32-SL module is developed by Encore Technology. The core processor

ESP32 of the module has a built-in low-power Xtensa®32-bit LX6 MCU, and the main

frequency supports 80 MHz and 160 MHz.

ESP32-SL specification V1.0

ESP32-SL adopts SMD package, which can realize the rapid production of products

through standard SMT equipment, providing customers with highly reliable connection

methods, especially suitable for modern production methods of automation, large-scale,

and low cost, and is convenient to apply to various IoT hardware Terminal occasions.
