LogicAnalizer: common questions

What microcontroller does the LogicAnalizer use?

The LogicAnalizer is built around the Sparkfun_Pro_Micro, from the AVR/Arduino family.

How big is the LogicAnalizer PCB?

The LogicAnalizer measures 148 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LogicAnalizer?

98 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the LogicAnalizer design files?

From the John-Lluch/SwitchBrain repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LogicAnalizer design in my own project?

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

Can I test firmware for the LogicAnalizer 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.
