Grape: common questions

What microcontroller does the Grape use?

The Grape is built around the ATMEGA328P_TQFP, from the AVR/Arduino family.

How big is the Grape PCB?

The Grape measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Grape?

84 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Grape design files?

From the FrizzyElectronics/Grape repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Grape design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Grape 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.
