Harp.device.environment sensor: common questions

What microcontroller does the Harp.device.environment sensor use?

The Harp.device.environment sensor is built around the RP2040, from the RP2040/RP2350 family.

How big is the Harp.device.environment sensor PCB?

The Harp.device.environment sensor measures 39.9 × 28 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Harp.device.environment sensor?

46 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Harp.device.environment sensor design files?

From the AllenNeuralDynamics/harp.device.environment-sensor repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Harp.device.environment sensor design in my own project?

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

Can I test firmware for the Harp.device.environment sensor 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.
