From the project

Kicad files for PCB production of easyhive boards which are used in easyhive hive scale.

1. Branch (master): Design with Nb-IoT Modul from ublox (SARA N310) 2. Branch: Design with Nb-IoT Modul from Quectel (BC66 04 Std)

Notes for Generate the bom of material: 1. copy file "easyhivebom.py" to your local KiCad Plugin folder e.g. /usr/share/kicad/plugins 2. Open Eeschema 3. Tools -> Generate Bill of Material: add a new plugin (choose easyhivebom.py) 4. Generate BOM! Path is your KiCad project directory

Easyhive: common questions

What microcontroller does the Easyhive use?

The Easyhive is built around the ATSAMD21G, from the Microchip SAM family.

How big is the Easyhive PCB?

The Easyhive measures 35 × 75 mm and is 1.6 mm thick.

How many components are on the Easyhive?

106 components, from 55 distinct parts. The full bill of materials is listed on this page.

Where can I download the Easyhive design files?

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

Can I use the Easyhive design in my own project?

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

Can I test firmware for the Easyhive without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
