Robo-328p: common questions

What microcontroller does the Robo-328p use?

The Robo-328p is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the Robo-328p PCB?

The Robo-328p measures 90 × 78 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Robo-328p?

50 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Robo-328p design files?

From the eavcodes/robo-328p repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Robo-328p design in my own project?

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

Can I test firmware for the Robo-328p without the hardware?

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