ESP32-S SMD38 Package

ESP32-S SMD38 Package


ESP32-S is an ultra-small multifunctional RF module independently designed and developed by Ai-Thinker.

It uses dual-core ESP32 as the main control, and the module is matched with the PCB on-board antenna and the IPEX antenna to be used according to the scene requirements.


It uses ESP32 chip, integrated Wi-Fi, traditional bluetooth and bluetooth low energy (BLE Beacon), with 2 high-performance 32-bit LX6 CPU, 7-stage pipeline architecture, main frequency adjustment range 80MHz to 240MHz, on-chip Sensor: Hall sensor, temperature sensor, etc.

It is fully compliant with WiFi 802.11b/g/n/e/i and Bluetooth 4.2 standards. It can be used as a master mode to build a stand-alone network controller, or it can be used as a slave to other host MCUs to add networking capabilities to existing devices.
