CPU Education Board

Story

I asked them to implement a CPU learning board. To keep costs down, they researched inexpensive LCDs in advance and created a board to match. Thanks to them, we were able to create it very cheaply, and I'm very pleased.

Working great!

If you know Home Assistant, you shouldn't have a problem getting these working. Programming isn't for beginners! But can all be done through ESPHome. My only hiccup was some coding issues, which I've emailed the developer about, to adjust the documentation. There was an issue with where the images should be in the code. I've upgraded one of the batteries to a 2Ah, and also added a 5v 75MaH solar panel to another. Both work great. I can't figure out how to get second pages to work. I'd like to add an info page for each plant. Could also do with a blank template for the display image. I Photoshopped my own version using the default one in the files, added my own fonts, etc. I also changed the position of the date and time in the code as they were misaligned a little with icons.

Professional quality pcb

I have used their service for my first ever PCB fabrication. My first pleasant surprise was the packaging, it is really on a high and professional level. All PCBs came vacum packed- bubble wrapped. The quality of the pcb is really on a high level. Pads, traces, holes all are crisp and like on the drawing. Silk screen is also of nice quality. I'd compare their PCBs to PCBs that are used in commercial/ professional products. I also like their shipping options, and the delivery time is fast. The customer service is also kind, and they respond back quickly. I'm happy with the service, I placed another order. I will be using it again, I can recommend Elecrow!

Good service

Good service as always. Assembly was a bit longer then it was supposed, but the order was made during the holydays. Lynn was always prompt to keep me informed. The placement of component and the connector where perfect for the mating.
