PlantWateringDevice: common questions

What microcontroller does the PlantWateringDevice use?

The PlantWateringDevice is built around the PIC10F202-IOT, from the PIC family.

How big is the PlantWateringDevice PCB?

The PlantWateringDevice measures 48 × 45 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the PlantWateringDevice?

44 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the PlantWateringDevice design files?

From the RobertGawron/PlantWateringDevice repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PlantWateringDevice design in my own project?

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

Can I test firmware for the PlantWateringDevice without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
