The ESP32-WROOM-32 is a system-on-chip (SoC) which integrated WiFi and Bluetooth. It has the advantage of industry-leading RF performance, low power consumption and high integration. The ESP32-WROOM-32 integrates complete transmit/receive RF functions including antenna switches, RF balun, power amplifiers, low noise amplifiers, filters, power management modules and advanced self-calibration circuits. The self-calibration circuit implements dynamic auto-tuning to eliminate defects in external circuitry. The ESP32-WROOM-32 features two 32-bit, LX6 CPUs with a clock speed of up to 240MHz and a 7-stage pipeline architecture. The ESP32-WROOM-32 also integrates a rich analog sensing and digital interface.
The ESP32-WROOM-32 WiFi module is designed and developed by Ai-Thinker. The core processor ESP32-WROOM-32 provides a complete set of 802.11 b/g/n/e/i wireless local area network (WLAN) and Bluetooth 4.2 solution. The solution has a small physical size. Designed for low-power and mobile consumer electronics, wearable and IoT devices, this chip integrates all the features of WLAN and Bluetooth on-chip, with low cost and good layout. ESP32-WROOM-32 also provides an open platform that allows users to flexibly customize functions for different application scenarios.
