The ESP32 Agent Dev Kit is an ESP32-S3-powered voice assistant that offers integrations with popular LLM models such as ChatGPT, Gemini, and Claude.
Wireless-Tag says the Dev Kit is suitable for “95% of AIoT applications, from smart home devices to desktop toys, robotics, and instruments”
In some ways, it is similar to the SenseCAP Watcher, but it has a larger, non-touch display and dual mic input. It however does not support local language models. It also features a standard MikroBUS interface for expansion.
For voice capabilities, the ESP32 Dev Kit integrates two onboard, noise-reducing microphones and a high-fidelity speaker. The built-in infrared laser proximity sensor detects human proximity and movement for “smart interactive experiences”.

The ESP32 Agent Dev Kit supports Arduino IDE and ESP-IDF development platforms and offers real-time interaction via Volcano Engine RTC and OpenAI’s Realtime API. It supports ChatGPT, Claude, and Gemini via the Coze AI platform.
Although the device is marketed as open-source, the GitHub repository has limited information. The product firmware is in binary format and the driver code written in C is provided as a tarball which defeats the purpose of using a version control system like git…
The crowdfunding campaign is live on Kickstarter and has surpassed its $1,668 US funding goal with several days to go. The product is offered for $40 on Kickstarter, with a target retail price of $69. It is slightly less expensive than the earlier-mentioned SenseCAP Watcher but has fewer notable features. Shipping is expected to begin in March 2025.
