## FAQ

**What microcontroller does the Sipeed MaixCAM-Pro use?**

The Sipeed MaixCAM-Pro is built around the SG2002.

**How many GPIO pins does the Sipeed MaixCAM-Pro have?**

16 GPIO pins are exposed. Xirkit documents 24 board pins, 16 of them with pin-level electrical limits.

**Are the Sipeed MaixCAM-Pro 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: ≥ 2.063 V.

**How much current can a Sipeed MaixCAM-Pro GPIO pin source?**

Documented output-high current per pin: 5–10.5 mA. Values are traced to the chip datasheet; see the pinout table for per-pin limits and conditions.

**What voltage powers the Sipeed MaixCAM-Pro?**

Supply range 5.5–5.5 V. Power inputs: VSYS, VBUS.

**How much does the Sipeed MaixCAM-Pro cost?**

From $133.71 at Ai-Paipai. Prices are observed unit prices before tax and shipping.

**What are the Sipeed MaixCAM-Pro dimensions?**

56.48 × 41.07 mm. A STEP model is available for enclosure fit checks.

**Which interfaces does the Sipeed MaixCAM-Pro support?**

gpio, spi, uart, pwm, i2c, debug.

**How do I program the Sipeed MaixCAM-Pro?**

Supported frameworks: MaixPy, MaixCDK, MaixVision.

**Where does this Sipeed MaixCAM-Pro data come from?**

Every value in this record is traced to a source — 2 documents including the board and chip datasheets — with the page and table cited per value. Unknowns are left explicit, never guessed.
