GpsLoggerLoRa: common questions

What microcontroller does the GpsLoggerLoRa use?

The GpsLoggerLoRa is built around the ATSAMR34J18B, from the Microchip SAM family.

How big is the GpsLoggerLoRa PCB?

The GpsLoggerLoRa measures 40.9 × 72.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the GpsLoggerLoRa?

110 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the GpsLoggerLoRa design files?

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

Can I use the GpsLoggerLoRa design in my own project?

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

Can I test firmware for the GpsLoggerLoRa 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.
