Frequently Asked Questions

What's the difference between the ESP32-S3 SuperMini and the ESP32-C3 SuperMini?
The S3 has a dual-core processor (vs. single-core RISC-V on the C3), offering more processing power for demanding applications, while both share a similar size and power profile.

Do I need an external programmer (e.g. FTDI) to program it?
No — the ESP32-S3 SuperMini has native USB, so it connects directly to your computer via USB without needing a separate USB-to-serial chip.

How low is the deep sleep consumption?
As low as ~43µA, making it well suited to battery-powered applications requiring long runtime.
