he ESP-32S Wi-Fi/Bluetooth module combines high wireless performance with low-power consumption in a deeply integrated and prototyping friendly SoM. Based on the ESPRESSIF ESP32 chipset, this module integrates a dual-core Xtensa 32-bit processor with 448 KBytes of ROM, 520 KBytes of SRAM, an RTC, 802.11 b/g/n/e/I Wi-Fi, Bluetooth v4.2 BR/EDR & BLE, clocks, timers, and a hardware crypto engine.



ESP32 is a brand new single chip 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC ultra low power 40 nm technology that is the successor to the legendary ESP8266. It is optimized for the best power and RF performance, robustness, versatility, features and reliability, for a wide variety of applications, and different power profiles. This is a brand new part and the documentation in English is not yet complete which makes this a perfect part to group buy and collaboratively hack on.

ESP32 is the most integrated solution for Wi-Fi + Bluetooth applications in the industry with less than 10 external components. ESP32 integrates the antenna switch, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules. As such, the entire solution occupies minimal Printed Circuit Board (PCB) area.

ESP32 is designed for mobile, wearable electronics, and Internet of Things (IoT) applications. It has many features of the state-of-the-art low power chips, including fine resolution clock gating, power modes, and dynamic power scaling.



This module is not recommended for new designs, only experimentation. The supply chain for this part is wildly unpredictable and we do not intend to stock more.
