1. OVERVIEW
1. Overview
ESP32 is a single 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC ultra-low-power 40 nm technol-
ogy. It is designed to achieve the best power and RF performance, robustness, versatility, and reliability in a wide
variety of applications and different power profiles.
ESP32 is a highly-integrated solution for Wi-Fi + Bluetooth applications in the IoT industry with around 20 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 uses CMOS for single-chip fully-integrated radio and baseband, and also integrates advanced calibration
circuitries that allow the solution to dynamically adjust itself to remove external circuit imperfections or adjust to
changes in external conditions. As such, the mass production of ESP32 solutions does not require expensive and
specialized Wi-Fi test equipment.
The ESP32 series of chips include ESP32-D0WDQ6, ESP32-D0WD, ESP32-D2WD and ESP32-S0WD. For details
