The ESP32-S31-Function-CoreBoard-1 offers 16 MB of PSRAM, wired Ethernet, and audio capabilities, while the ESP32-S31-Korvo-1 includes a camera, LCD display, and microphones for smart display prototyping. Both kits support Wi-Fi 6, Bluetooth 5.4, Thread, and Zigbee, though pricing and availability have not yet been announced.", "body_md": "Espressif just pulled the wraps off two fresh development kits aimed at one of its most ambitious chips yet: the dual-core RISC-V ESP32-S31. If you've been waiting for a board that blends heavy IoT muscle with edge AI capability, this pair is worth a long look.\n\nThe new chip pairs two RISC-V cores in a heterogeneous setup. One runs up to 320 MHz for performance-hungry workloads, while the other sips power for everyday microcontroller chores. Espressif is pitching it at advanced IoT, machine learning inference, computer vision, and smart audio — all from a single chip with 60 GPIOs to spare.\n\nOn the radio side you get Wi-Fi 6 on 2.4 GHz, Bluetooth 5.4 Classic and Low Energy, plus an 802.15.4 radio with Thread and Zigbee. There's even an integrated gigabit Ethernet MAC, which is rare for an ESP32. RAM-wise, you're looking at 512 KB of on-chip SRAM and an eight-bit 250 MHz DDR bus for external PSRAM. One core also packs a 128-bit data path with SIMD for parallel number crunching.\n\nThe ESP32-S31-Function-CoreBoard-1 is the workhorse. It carries 16 MB of PSRAM, a choice of 8, 16, or 32 MB of flash, an on-board microphone, a mono audio codec with amplified speaker output, wired Ethernet, USB 2.0 High Speed Type-A and Full Speed Type-C ports, a 40-pin GPIO header, a built-in current measurement header, and a user-addressable RGB LED. Ideal if you want to prototype anything from sensor hubs to networked controllers.\n\nThe ESP32-S31-Korvo-1 trades Ethernet for human-machine interface (HMI) gear. The same module — this time with 16 MB of flash — is wired to an Omnivision OV3660 camera, a 4.3-inch 800×480 LCD, two independent speaker outputs, two analog microphones, four user buttons, an RGB LED, a microSD slot, and USB Type-A and Type-C. It's basically a ready-made smart display reference design.\n\nWant to hack on one of these straight away? You'll need the ESP32-S31 module itself, and depending on which board you're cloning: an Omnivision OV3660 camera module, a 4.3-inch 800×480 LCD panel, analog microphones, a mono audio codec and speaker driver, a microSD card slot, and USB Type-A plus Type-C ports. Pricing and general availability haven't been confirmed yet, but Espressif's documentation pages for the CoreBoard and Korvo are already live.\n\n*Originally published on blog.circuit.rocks.*", "url": "https://wpnews.pro/news/espressif-reveals-coreboard-and-korvo-dev-kits-for-esp32-s31", "canonical_source": "https://dev.to/circuitrocks/espressif-reveals-coreboard-and-korvo-dev-kits-for-esp32-s31-1egm", "published_at": "2026-05-26 01:05:54+00:00", "updated_at": "2026-05-26 01:33:30.881659+00:00", "lang": "en", "topics": ["ai-chips", "machine-learning", "computer-vision", "artificial-intelligence", "ai-products"], "entities": ["Espressif", "ESP32-S31", "CoreBoard", "Korvo", "RISC-V", "Wi-Fi 6", "Bluetooth 5.4", "Thread"], "alternates": {"html": "https://wpnews.pro/news/espressif-reveals-coreboard-and-korvo-dev-kits-for-esp32-s31", "markdown": "https://wpnews.pro/news/espressif-reveals-coreboard-and-korvo-dev-kits-for-esp32-s31.md", "text": "https://wpnews.pro/news/espressif-reveals-coreboard-and-korvo-dev-kits-for-esp32-s31.txt", "jsonld": "https://wpnews.pro/news/espressif-reveals-coreboard-and-korvo-dev-kits-for-esp32-s31.jsonld"}}
