Just finished your XIAO ESP32-C5 video and it’s such a great deep dive—this little board is an absolute steal for under $7, and Seeed really nailed packing all that ESP32-C5 functionality into the XIAO form factor. Dual-band Wi-Fi 6, BLE 5, plus Matter/Zigbee/Thread support is a killer combo for compact IoT builds, and the onboard LiPo charging + deep sleep power management? Total game-changer for battery-powered projects, exactly what we need for small-form-factor IoT gear.

 

Loved the dual-band Wi-Fi analyzer build too—tweaking the display library sample code makes it the perfect first project to test that 5GHz capability right out the gate. From what I’ve tinkered with the ESP32-C5 core, its 5GHz performance is surprisingly solid for its size (way better than I expected), even if it’s a bit sensitive to physical obstructions like most 5GHz modules. This analyzer build is perfect for real-world testing that, such a smart use of the board’s strengths.

 

I had one quick thought/question while watching that I’m curious to hear your take on: the single-core 240MHz MCU is more than enough for basic IoT use cases, but have you tried running concurrent connectivity (Wi-Fi 6 + Zigbee/Thread) with a light sensor load on it yet? Wondering how it handles the multi-protocol overhead—my hunch is it runs smooth for the compact builds this board’s designed for, but it’d be awesome to hear your real-world experience with it.

 

This board’s already shot to the top of my parts list for upcoming small IoT projects—thanks for the fantastic breakdown and practical build guide, it’s got me fired up to tinker with one! Yassin
