飛んでいる間の道具であり、飛んだあとの計測器でもあります。 当日の誘導と、次の機体の設計の両方に活用できます。

Pilot Oriented Navigation System: common questions

What microcontroller does the Pilot Oriented Navigation System use?

The Pilot Oriented Navigation System is built around the RP2350_80QFN, from the RP2040/RP2350 family.

How big is the Pilot Oriented Navigation System PCB?

The Pilot Oriented Navigation System measures 55.4 × 77.6 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the Pilot Oriented Navigation System?

120 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pilot Oriented Navigation System design files?

From the MasaoC/GPS-TFT-Map_PONS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pilot Oriented Navigation System design in my own project?

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

Can I test firmware for the Pilot Oriented Navigation System 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.
