Answers from the record

ESP32-S3-DevKitC-1 (N8R8) pinout FAQ

What microcontroller does the ESP32-S3-DevKitC-1 (N8R8) use?

The ESP32-S3-DevKitC-1 (N8R8) is built around the ESP32-S3R8, alongside ESP32-S3-WROOM-1-N8R8, SGM2212-3.3XKC3G/TR, CP2102N-A02-GQFN28, SK68XXMINI-HS.

How many GPIO pins does the ESP32-S3-DevKitC-1 (N8R8) have?

36 GPIO pins are exposed. Xirkit documents 44 board pins, 37 of them with pin-level electrical limits.

Are the ESP32-S3-DevKitC-1 (N8R8) I/O pins 5 V tolerant?

No. The I/O pins are not 5 V tolerant — they run at 3.3 V logic; use a level shifter for 5 V signals. Input-high threshold: 2.475–3.6 V.

How much current can a ESP32-S3-DevKitC-1 (N8R8) GPIO pin source?

Documented output-high current per pin: 40 mA typ. Values are traced to the chip datasheet; see the pinout table for per-pin limits and conditions.

What voltage powers the ESP32-S3-DevKitC-1 (N8R8)?

Supply range 5–5 V. Power inputs: 5V.
