Espressif Systems ESP-Claw framework builds local AI agents for ESP32 devices

ESP Claw ESP32 RGB LED Strip demo

We had already seen OpenClaw-like AI agents for ESP32 targets such as Mimiclaw and PycoClaw, but Espressif Systems has released its own ESP-Claw framework for building local AI agents capable of LLM-driven interaction and execution on ESP32 devices. ESP-Claw enables ESP32 boards to respond to events, work with LLM-driven decisions, retain useful context, and take actions locally without connection to the cloud, unless required. The agent can control sensors and device state, and perform real-world actions such as controlling an RGB LED strip. Some highlights of ESP-Claw include: Chat coding – Define device behavior through natural conversation. The LLM handles dynamic decisions, and local Lua scripts execute deterministically, even when offline. Quick response time – Devices react to real-time events instead of polling. A local event bus drives Lua rules for sensors and triggers, enabling millisecond-latency response on or offline. Plug and Play with MCP –  ESP-Claw acts as both […]

SparkFun Thing Plus – ESP32-C5 board offers dual-band WiFi 6, Adafruit Feather pinout, LiPo battery support

SparkFun Thing Plus ESP32 C5

Espressif has recently released the ESP-IDF v6.0 framework with support for ESP32-C5 and ESP32-C61, so we can expect more ESP32-C5 boards. Following the launch of boards like DFRobot FireBeetle 2 and the Espressif DevKitC-1, SparkFun has now launched its Thing Plus – ESP32-C5, an Adafruit Feather-compatible board based on the ESP32-C5. The timing is no coincidence. Although the ESP32-C5 dual-band WiFi 6 SoC was announced back in 2022, hardware makers have been waiting for stable software support. With the release of ESP-IDF v6.0, the ESP32-C5 moves from “preview” to “stable” and adds key features, such as Safe Bootloader OTA updates. This enables the ROM bootloader to fall back to a recovery partition if an update fails, making it reliable enough for companies like SparkFun to launch hardware for remote deployments and Matter-compatible smart home applications. SparkFun Thing Plus – ESP32-C5 specifications: Wireless module –  ESP32-C5-WROOM-1 SoC – Espressif Systems ESP32-C5 CPU Single-core […]

ESP32-E22 WiFi 6E SoC

Espressif Systems is showcasing its products at CES 2026, including two interesting upcoming parts: the ESP32-E22 Wi-Fi 6E tri-band SoC and the ultra-low-power ESP32-H21 Bluetooth LE MCU for battery-powered devices. Espressif Systems has been teasing an upcoming Wi-Fi 6E SoC for several months, but so far, there have been very few details. Once tipped that the ESP32-E22 tri-band Wi-Fi 6E SoC was demonstrated at CES 2026, I headed over to X and noticed tks posted a few interesting photos from the exhibition. Here’s what we know about the ESP32-E22 so far: CPU – Dual-core RISC-V processor at up to 500 MHz Memory – 1 MB (no optional PSRAM) Wireless Tri-band 2.4/5/6GHz Wi-Fi 6E, 160 MHz channel bandwidth, 2×2 MIMO; tested with iperf; up to 2.1 Gbps physical thoughput Dual-mode Bluetooth 5.4/6.0 (LE + BR/EDR) I/Os – 41x GPIO Host interfaces – PCIe 2.0, USB FS OTG, SDIO 3.0 (when used […]

The ESP Private Agents platform aims to ease the development of ESP32-based AI voice assistants with on-device processing

ESP32 AI Agent Translator Interpreter

Espressif has just introduced the ESP Private Agents platform to help developers build local, private, and customizable AI assistants for ESP32 devices running on-device, although they can also support hybrid AI workloads with a mix of on-device and cloud processing. The ESP Private Agents platform offers a unified framework that allows developers to build applications combining speed, vision, automation, and agent-based interactions, for example, a multi-lingual, on-device voice agent (aka smart speaker) or task-oriented agents that automate workflows. The solution is built on AWS cloud services using AWS Fargate as a primary application platform and Amazon Bedrock Foundation Models as backend LLM systems. It not only works with ESP32-power devices with speaker and microphone, but also with mobile apps and web clients. Espressif released a Web-based demo, which you can use as a text-based chatbot or as a voice assistant leveraging the speaker and microphone on your computer. The company […]
