From the project

AI quadcopter on one RV1103 (Luckfox Pico Mini B): Linux + RISC-V MCU flight loop, SITL with 3D pilot view, KiCad flight-controller board

Nguyên mẫu quadcopter dùng một chip Rockchip RV1103: - Cortex-A7 chạy Linux: camera, NPU nhận dạng, Wi-Fi, GPS, bộ thu RC. - Lõi MCU RISC-V (HPMCU) chạy RT-Thread: vòng điều khiển bay 1 kHz.

Mục tiêu dự án là trả lời bằng số liệu đo được: kiến trúc một chip có bay được không. Nếu không, phương án B là thêm một MCU điều khiển bay rời.

LFX FC R2: common questions

What microcontroller does the LFX FC R2 use?

The LFX FC R2 is built around the Luckfox Pico Mini B, from the RP2040/RP2350 family.

How big is the LFX FC R2 PCB?

The LFX FC R2 measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LFX FC R2?

113 components, from 65 distinct parts. The full bill of materials is listed on this page.

Where can I download the LFX FC R2 design files?

From the nguyencanhanh/luckfox-rv1103-drone repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LFX FC R2 design in my own project?

Yes, under the terms of its MIT license, which nguyencanhanh chose for the repository.

Can I test firmware for the LFX FC R2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
