CaiPad25: common questions

What microcontroller does the CaiPad25 use?

The CaiPad25 is built around the Arduino_Pro_Micro, from the AVR/Arduino family.

How big is the CaiPad25 PCB?

The CaiPad25 measures 131.4 × 99.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CaiPad25?

52 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the CaiPad25 design files?

From the Luminat3/CaiBoard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CaiPad25 design in my own project?

The repository has no license, so all rights stay with Luminat3. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CaiPad25 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.
