📝 ESP32-E22: Key Specifications

If you were wondering about its use case, well, it is said to be a good fit for smart home hubs, AR/VR accessories that need low-latency wireless performance, high-bandwidth streaming, wireless video links, and industrial automation.Of course they are not limited to just that. Expressif also supplies industrial-grade SoCs, Modules, and DevKits for commercial deployments.A recent announcement sees them adding a new SoC to their lineup.Suggested Read 📖: 11 Interesting ESP32 Microcontroller ProjectsDubbed a Radio Co-Processor (RCP), the ESP32-E22 can handle wireless connectivity while a separate host processor runs application code. It is powered by a dual-core 500 MHz RISC-V processor that was developed by Espressif.For external connectivity, there’s high-speed interfaces like SDIO 3.0 and PCIe 2.1, with Expressif claiming that it can efficiently handle wireless data transfer rates up to 2.4 Gbps using 1024-QAM modulation.There’s a but here though.
The chip supports tri-band Wi-Fi 6E across 2.4 GHz, 5 GHz, and 6 GHz frequencies, and comes with dual-mode Bluetooth support for both Classic (BR/EDR) and Bluetooth Low Energy 5.4.
