🔆 SunFounder R3 Board: Enhance Arduino Projects with ATMEGA328P & ATMEGA16U2 Review

First off, the case is cheap Plexiglas, not Lexan! At the same time, compared to Lexan, Plexiglas is extremely fragile and breaks quite easily! Second, someone has to recalibrate the CNC machine that cuts them because my case wasn't assembled properly and it put unnecessary stress on the parts. ! I have some editing experience so I know what I'm talking about! When I assembled the case I went right to plan and don't you know as soon as I started tightening the screws part of the case broke off…

5 stars except that the part for the reset button was missing. Instead, I received two pieces of a stabilizer bar. However, this was not a big problem; I just filed it into the right shape and everything was fine. However, if this happens frequently, there must be a QA issue. Otherwise I will overcome my doubts and say that it was just an accident. Although everything fits perfectly, it can be a bit of a hassle to get everything in the right place.

This is a useful addition to the Arduino Uno as there is little risk of shorting out the back of the PCB when experimenting on a table top. It is well made, has sharp edges and fits perfectly on the Uno PCB. All I/O and power pins are accessible, as is a reset button. It is crystal clear and reading the silkscreen on the board and the onboard LEDs is very easy.

I've tried different cases and the Sunfounder is the best! I use the blade of a small knife and start (slowly) peeling off the protective layer from the corner. Secure the reset button with tape during final assembly. The case fits like a glove to support and protect your board and the shields fit securely on top of the case. I attached small silicone feet to the underside so that it does not slip or scratch.

Excellent case. Thanks to the recess for the Atmel chip, the pin headers are flush with the top of the case. This allows shields to be placed on the board. They also provide an extension for the reset button, as well as standoffs to support the board. I've used UNO and MEGA cases and they work great. They also have holes for attaching the case. This can be very handy if you want to attach the case to or in something. I recently received a similar case for free (not SunFounder) with my UNO…

The case fits snugly and works very well. I've been using it almost daily for my college classes for several months. I no longer worry about my Arduino UNO getting damaged in my tool bag. This damn thing took forever to put together and it took me four hands! However, the result was worth the effort. The diagram of how to put it together could have been better as it took two brains and four hands :/ But five stars because I figured it out, put it together and it safely protects my Arduino while
