Got some exciting news — Espressif just dropped the ESP32-S31 , their most capable IoT chip yet. And it's a pretty big deal. What's Inside CPU : RISC-V dual-core @ 320 MHz with SIMD instructions Wireless : Wi-Fi 6 (2.4 GHz), Bluetooth 5.4 (LE Audio + Classic), IEEE 802.15.4 (Thread + Zigbee) Wired : Built-in Gigabit Ethernet Memory : 512 KB SRAM + up to 250 MHz PSRAM support Security : Secure boot, memory encryption, cryptographic acceleration, TEE Protocol : Full Matter protocol support Why This Matters 1. RISC-V Architecture For the first time, Espressif chose RISC-V over Xtensa for a high-end ESP32 chip. RISC-V is an open ISA — meaning anyone can build toolchains, compilers, and libraries without vendor restrictions. The community can innovate freely. 2. All the Protocols in One Chip Wi-Fi 6 + Bluetooth 5.4 + Thread + Zigbee + Ethernet — all in one package.…
