ESP32-E22 is Espressif's first tri-band Wi-Fi 6E connectivity co-processor, designed for host-based wireless systems operating across the 2.4 GHz, 5 GHz, and 6 GHz bands. Built as a Radio Co-Processor (RCP), it offloads Wi-Fi and BT protocol processing from the host, enabling flexible system architectures with Espressif or third-party processors. Based on self-developed dual-core RISC-V platform and in-house Wi-Fi 6E stack, ESP32-E22 provides a stable, scalable connectivity foundation for next-generation products.
