9 The ESP32-S3-DevKitM is an entry-level development board equipped with either ESP32-S3-MINI-1
10 or ESP32-S3-MINI-1U, a module named for its small size. This board integrates complete Wi-Fi
11 and Bluetooth Low Energy functions. For more information, check `ESP32-S3 DevKitM`_
16 ESP32-S3 is a low-power MCU-based system on a chip (SoC) with integrated 2.4 GHz Wi-Fi
17 and Bluetooth® Low Energy (Bluetooth LE). It consists of high-performance dual-core microprocessor
18 (Xtensa® 32-bit LX7), a low power coprocessor, a Wi-Fi baseband, a Bluetooth LE baseband,
21 ESP32-S3 DevKitM includes the following features:
23 - Dual core 32-bit Xtensa Microprocessor (Tensilica LX7), running up to 240MHz
