ESP32-C6
ESP32-C6
Summary
A RISC-V microcontroller with Wi-Fi 6, Bluetooth LE and native 802.15.4 (Thread and Zigbee). Notable against older ESP32 variants for lower deep-sleep current, which is the number that decides battery life on anything that wakes periodically.

Key Facts
- Deep-sleep current is materially lower than the C3, which is the reason to pick it for battery builds
- Native 802.15.4 means Thread without an extra radio — useful even if you don’t use it today
- Wi-Fi 6 support is largely irrelevant at this scale; don’t let it drive the decision
When to Use
Pick it when the device sleeps most of the time and runs on a battery. If the device is mains powered, the deep-sleep advantage doesn’t apply and a cheaper variant is fine.
Compared To
Against the ESP32-C3: better sleep current, native Thread, slightly higher cost. Against the ESP32-S3: the S3 has more RAM and USB-OTG, which matter for displays and audio; the C6 wins on power. Choose by whether the constraint is compute or battery.
