AMR Krabbler: common questions

What microcontroller does the AMR Krabbler use?

The AMR Krabbler is built around the Arduino_Nano_v3.3, from the AVR/Arduino family.

How big is the AMR Krabbler PCB?

The AMR Krabbler measures 38 × 47 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AMR Krabbler?

16 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the AMR Krabbler design files?

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

Can I use the AMR Krabbler design in my own project?

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

Can I test firmware for the AMR Krabbler 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.
