Review: Powerful Little Board for IoT and AI Projects! - The Seeed Studio XIAO ESP32 S3 Sense is an excellent compact board packed with features. Built-in Wi-Fi and BLE 5.0 make connectivity seamless, and the OV2640 camera plus digital microphone open up lots of possibilities for vision and audio-based projects. Having both 8MB PSRAM and 8MB Flash is a huge advantage for running more complex applications, including embedded ML. I really like the small form factor—it’s easy to integrate into IoT projects—and the fact that it supports battery charging makes it super practical for portable solutions. The interfaces are rich and well-documented, so getting started was smooth. Overall, this is a very capable and affordable development board for IoT, AI, and edge ML experiments. Highly recommended for makers, hobbyists, and developers!
Review: Amazing value and dead simple to use - Great little boards and incredible value for the money. Perfect for ESPHome. Dead bug it or solder onto a protoboard with the castellated pads. I didn’t realize it had a built-in battery circuit, have not messed around with that but I intend to try it out sometime. No temp wire makes me nervous though. Can’t get easier to program and flash than ESPHome builder- Claude code can just spit out the yaml you need and you’re up and running in seconds. Comes with little WiFi antennas but I actually found the reception isn’t too bad without it.
