Overview
The MKR2UNO Adapter allows you to turn your Arduino UNO form factor based project into a MKR based one without too much effort! You can so upgrade your project with a powerful board with integrated LiPo battery charger.
Please note that currently the MKR2UNO adapter is compatible only with MKR1000 without headers

Please keep in mind that the MKR2UNO is just a form factor adapter and so is NOT present any voltage translation. Be careful before connecting a shield since shield without IOREF level shifting capability may not work properly.
Like in many others Arduino boards this adapter allows to power your MKR board using a barrel jack with center positive polarity or the VIN pin on the headers.
Unlike the Arduino UNO, the MKR2UNO Adapter do NOT have I2C signals on A4 and A5 and SPI on pins 11, 12 and 13.
All the pins on the MKR2UNO Adapter are wired one to one from the MKR to the UNO form factor with some exception:

We are excited to announce our team will be traveling to Amsterdam for The Things Conference on September 22nd-23rd, where Arduino will be among select exhibitors. The Things Conference is the world’s largest conference about LoRaWAN®, bringing together the industry’s major players contributing to this technology’s development in a two-day deep dive dedicated to making business operations smarter. This year’s edition will focus on the main topic of digital transformation – as seen through the lens of LoRaWAN®, of course! Connect with us at The Things Conference Don’t miss your chance to meet our experts in person at Amsterdam’s The Kromhouthal – a former marine engine factory now turned into a unique event venue. We’ll be showcasing some of our best LoRaWAN® products and solutions: The Portenta Vision Shield LoRa®, designed to boost Arduino Pro’s H7 module with the capability to run embedded computer vision applications, connect wirelessly via LoRa® to the Arduino Cloud (or third-party infrastructure), and activate systems upon the detection of sound events; The Portenta Max Carrier, which can augment Portenta H7 or X8 with LoRa® connectivity and transform existing Arduino Pro modules into single-board computers or reference designs that enable edge AI for high-performance industrial, building automation and robotics applications;The Arduino MKR WAN 1310, an entry-level option featuring the renowned versatility of the MKR family: a practical and cost-effective solution to add LoRa® connectivity to projects requiring low power;Last but not least, the newly launched WisGate Edge Lite 2 and WisGate Edge Pro: ready-to-use, industrial-grade gateways for LoRaWAN® connectivity powered by RAKwireless™. On September 22nd, the packed schedule of The Things Conference also includes a keynote by Sebastian Romero, Lead Interaction Designer & Creative Technologist at Arduino: “Predictive Maintenance with an Arduino-based
