Ntp devboard: common questions

What microcontroller does the Ntp devboard use?

The Ntp devboard is built around the RP2040, from the RP2040/RP2350 family.

How big is the Ntp devboard PCB?

The Ntp devboard measures 42.4 × 51 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ntp devboard?

72 components, from 25 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 Ntp devboard design files?

From the vighnesh-sawant/ntp-devboard 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 Ntp devboard design in my own project?

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

Can I test firmware for the Ntp devboard 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.
