Michael Krumpus designed and built a SAMD21 development board with LoRa radio module and GPS receiver, that is available on GitHub:
I’ve been doing some LoRa projects lately in order to learn as much as I can about this exciting new radio technology (see this LoRa mesh networking project and this LoRa weather station). ATmega328-based Moteino modules work great for a lot of projects, but I wanted a LoRa node with more processing power, more memory, and an onboard GPS receiver. The ATmega328 is just too constrained with memory — I’ve outgrown it. I really wanted a LoRa board with an ARM Cortex microcontroller like the SAMD21. This is the microcontroller used on the Arduino Zero. So, my ideal board is a SAMD21 with LoRa radio module and GPS receiver, all programmable with the Arduino IDE.
But, where is such a board? I could not find one so I decided to design and make one myself.

I’ve been asked this question a couple times. How do you program an Atmel SAM MCU without a boot loader or the Arduino IDE? In this video I’ll show you how to do this using Linux and an Atmel In-Circuit Debugger. The Atmel SAM MCU The Atmel SAM MCUs are Continue reading Program an Atmel SAM without an IDE. // Tutorial

This week’s Weekly Roundup we’re seeing lots of 3D printing stuff, wireless modules and a gamers watch. Kickstarter Kickstarter is big on desktop fabrication this week. Solderdoodle Plus The Solderdoodle Plus is a follow on to a previous Kickstarter and is essentially a USB chargeable soldering iron that has an adjustable 15W heating element, an
