PARENT MAIN: common questions

What microcontroller does the PARENT MAIN use?

The PARENT MAIN is built around the Pico 2 W, from the RP2040/RP2350 family.

How big is the PARENT MAIN PCB?

The PARENT MAIN measures 112 × 88 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PARENT MAIN?

24 components, from 18 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 PARENT MAIN design files?

From the AquaBeacon/hardware 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 PARENT MAIN design in my own project?

Yes, under the terms of its Apache-2.0 license, which AquaBeacon chose for the repository.

Can I test firmware for the PARENT MAIN 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.
