NxtPX4V2: common questions

What microcontroller does the NxtPX4V2 use?

The NxtPX4V2 is built around the STM32H743VIH6, from the STM32 family.

How big is the NxtPX4V2 PCB?

The NxtPX4V2 measures 33 × 27 mm, has 4 copper layers and is 0.982 mm thick.

How many components are on the NxtPX4V2?

122 components, from 61 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the NxtPX4V2 design files?

From the ArduPilot/Schematics repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the NxtPX4V2 design in my own project?

The repository has no license, so all rights stay with ArduPilot. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the NxtPX4V2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
