This is a set of an Arduino UNO compatible board, a case, and a multi-function shield. I have used it a few times, but there are no noticeable scratches or stains. 【Condition of the product】 I have confirmed power-on and some functions, but I have not checked all pins and functions. Regarding the multi-function shield, you can find various information (sketches, circuit diagrams, etc.) by searching Google for "[Multi-Function shield]". The case seems to be for an Arduino UNO with a USB Type-B port, and for this product's Arduino UNO compatible board with a Micro USB Type-B port, the connector and the case slightly interfere with each other, making it difficult to insert the cable all the way in. You may need to shave off or remove the panel on the connector side to use it. The product includes the Arduino UNO compatible board, the case, and the multi-function shield. The AC adapter and USB cable used in photo 1 are not included. I am reusing packaging materials from my home. Thank you.
