I think this is a great project for beginning solderers. I like the robot design and I am looking forward to working with these with my students. My only complaint is that they do not come with the battery. I knew this was the case the I ordered but there was nothing indicating which battery I needed to order. Luckily I was able to find an old post for the badge on another website to get the information I needed. I would be willing to pay more if they came with the battery. But overall, great product. Thank you. These are going to light up our school makerspace lab!
I bought assembled cube. Perfomance is good. But I had small problem with documentation. I had to look on Google some description how to connect to arduino board and test sequence of LED for programming. Thank You.
I use this eInk display as test platform for u8g2 Arduino graphics library. Wiring is easy and the display works as expected. Only 4 stars for documentation, because the pin names are missing on the PCB (instead a paper description is included) and the original SSD1606 datasheet seems to be incomplete in some details. As stated in the description: The eInk display requires about one second for screen refresh. All in all a very nice display with great contrast, which keeps the content permanently (also during power off).
I finally got around to using this; I wanted a low power display that doesn't get updated very often (a few times a day at best) and this works great. Quality of the screen & backpack are great. It's clear they do a quality control check before they ship it out. If I need another paper white type screen, I would absolutely get another one.
