1. ESP32 integrates the antenna switches, 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.

2. ESP32 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.

Hybrid Wi-Fi & BT

ESP32 can perform as a standalone application or as a slave device to a host MCU. ESP32 can work with other systems to provide Wi-Fi and Bluetooth functionality through the SPI / SDIO or I2C / UART interfaces.

Low Power

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

Wide Operating Temperature Range

By integrating more components on-chip, we have made the solution to be the most robust and manufacturable. Our solutions also feature the widest operating temperature range, from -40°C to +125°C.
