DE10Jamma: common questions

What microcontroller does the DE10Jamma use?

The DE10Jamma is built around the Arduino 3-7, from the AVR/Arduino family.

How big is the DE10Jamma PCB?

The DE10Jamma measures 114.6 × 83.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DE10Jamma?

98 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the DE10Jamma design files?

From the MisterJamma/DE10Jamma repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the DE10Jamma design in my own project?

The repository has no license, so all rights stay with MisterJamma. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the DE10Jamma 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.
