ElaraGNSSMKRShield: common questions

What microcontroller does the ElaraGNSSMKRShield use?

The ElaraGNSSMKRShield is built around the ARDUINO_MKR, from the AVR/Arduino family.

How big is the ElaraGNSSMKRShield PCB?

The ElaraGNSSMKRShield measures 61.5 × 25 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ElaraGNSSMKRShield?

37 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the ElaraGNSSMKRShield design files?

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

Can I use the ElaraGNSSMKRShield design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the ElaraGNSSMKRShield 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.
