We have a nice PCB that allows you to make an Arduino (3.3V pro micro) project incorporating a ST7735 TFT display. The PCB is 80mm X 60mm and also has a place to mount a DS3231 RTC if needed. The TFT mounts on the reverse of the PCB, so the whole thing is neat and compact.
This is only a PCB (no other parts), but we send full wiring instructions.
See this PCB here.
Hi, yep - there are many ways to produce Arduino projects. The image you show is a nice-looking device.
The PCB we offer is simply a PCB, but it is specifically designed to mount a Pro Micro with an ST7735 TFT and an optional RTC, all in a compact space. It also allows for external inputs and even for the direct placement of an EV1527 remote receiver.
Overall, the builder could create a clock or another circuit that needs Pro Micro and ST7735. It would not accept the processor you show, sorry - just a Pro Micro.
Cheers
You may not be soliciting criticism, but one thing that would be an issue for me - I mount PCB's like this in enclosures, the power source and sometimes the interface is via the USB. That means I always locate the USB connector at the edge of the board, or even further out if I can, because it be behind a faceplate or housing wall. The user has to have access to the USB connector without having to go on a fishing expedition to find it. Most existing products (such as the Pro Micro) already have this figured out.
I respectfully accept that you would take a different design approach, but the PCB is what it is, and it is offered as such. I get that the PCB is clearly not something you would choose. But it might be useful for others.
The PCB was designed for a specific purpose and I have some spares to offer.
Regarding power, there is a 2-pin JST connector for a 5V power connection. The original project has the power entry on the rear of the enclosure so that it was hidden (i.e. not visible on the side), so positioning the Micro close to the edge was not necessary for that project.
The project was a clean design with no holes in the side for anything; hence, the PCB is even designed to take an EV1527 remove control receiver, again to avoid any extra holes in the enclosure for (e.g.) buttons.
The project was powered with USB, but using a USB bezel on the rear of the enclosure, where it was out of sight.
I hope this helps.
