The Arduino MKR family typically costs between $25 and $38 the UNO family typically costs between $23 and $45. Projects where the MKR is better and projects where the UNO is better.I’ve included a full guide below comparing UNO and MKR on the following items: My Arduino UNO WiFi Rev 2, I chose it over an MKR due to the greater shield compatibility
I’ve included more details on technical specs below. MKR boards operate at 3.3V which means that many shields will not work when connected to an MKR board. Most shields are designed for an operating voltage of 5V, which UNO boards operate at. MKR boards are not compatible with many shields due to their lower operating voltage. Interested in a comparison of the best Arduino boards for beginners? I wrote a whole comparison guide for all the different options here: /best-arduino-for-beginners/ I’ve included examples of good projects for UNO and MKR boards below. This is due to the UNO having a greater shield compatibility than the MKR family. While UNO boards are better for projects that involve utilising Arduino shields, such as display panels and motors. In general, MKR boards are better for use in projects that communicate with the cloud, such as collecting data from sensors and uploading it to cloud services. UNO boards cost between $23 and $45 and only include WiFi and Bluetooth on the more expensive boards. MKR boards typically cost between $32 and $38 and mostly include WiFi and Bluetooth. The main difference between UNO and MKR is that MKR boards are designed for cloud connectivity and Internet of Things projects, while UNO boards are designed for general-purpose prototyping with the widest range of compatibility. This wasn’t an easy decision so I’m sharing in this guide a summary of the research that I put into figuring out if I should buy an UNO or an MKR. When looking for a new Wi-Fi ready Arduino recently, I was given the choice of an UNO or an MKR.
