Answers from the record
Luckfox Pico Ultra W pinout FAQ
What microcontroller does the Luckfox Pico Ultra W use?
The Luckfox Pico Ultra W is built around the RV1106G3, alongside eMMC 8G.
How many GPIO pins does the Luckfox Pico Ultra W have?
30 GPIO pins are exposed. Xirkit documents 52 board pins, 28 of them with pin-level electrical limits.
Are the Luckfox Pico Ultra W 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 V.
How much current can a Luckfox Pico Ultra W GPIO pin source?
Documented output-high current per pin: not specified in the RV1106 datasheet — drive strength is software-configurable, no IOH/IOL table. Values are traced to the chip datasheet; see the pinout table for per-pin limits and conditions.
What voltage powers the Luckfox Pico Ultra W?
Supply range 5–5 V. Power inputs: 5V, 5V, VCC5V0_SYS.
