Harp Device ID: 1411 Harp Events Waveform Start (per-channel) Waveform Finished (per-channel)
These printed circuit boards are made on-demand.
Setting up and playing a waveform is a simple process for each Analog Output (AO) channel. 1. Specify any external input trigger conditions for the output channel. 2. Specify the waveform Player. 3. Specify the Player's settings. 4. Wait until the Player is ready (< 50[ms] of wait time for the player to apply the settings and arm the waveform). 5. Trigger the Player either via software command or by applying external input to the corresponding…

Harp.device.quac: common questions
What microcontroller does the Harp.device.quac use?
The Harp.device.quac is built around the RP2350_80QFN, from the RP2040/RP2350 family.
How big is the Harp.device.quac PCB?
The Harp.device.quac measures 90 × 100 mm, has 4 copper layers and is 1.567 mm thick.
How many components are on the Harp.device.quac?
276 components, from 65 distinct parts. The full bill of materials is listed on this page.
Where can I download the Harp.device.quac design files?
From the AllenNeuralDynamics/harp.device.quac 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.quac 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.quac 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.
