As I written this post for another target and it can be also useful for anyone, even if It is one more post on many of them, here are a couple of words about Meltdown and Spectre security issues. Read mode for details.

There are different type of smd capacitor ; the one I mainly use are mlcc – multi layer ceramic capacitor. In this technology, there are different dielectric (NP0, X7R, X5R, Y5V) with different characteristics.
I was looking for informations about this and found different nice website. I’ll try to summarize what I found in this post.
The TD1205 device is more than the usual Telecom Design Sigfox embedded circuit as TD1204 and TD1208, they are a all in one chip providing GPS antenna and RF antenna. Ready to use, to be clear you just need to plug a battery to use it.
In my point of view, for many applications not requiring more than 2 GPIOs, this product is really easy and chip way to design a SigFox product. As it costs around 55$ and you just have to add box & battery id sounds like the most affordable for small quantities. But …
This post is detailing what is specific to this chip ; read more following the link
I recently created a printed circuit board for a raspberry PI design i’m working on. By the past, when I did such things, the cost to make it was not accessible for a home made design. In 10 years things have change a lot and now, you can do it for less than 100€ for a 10×10 two layer board. 4 layer is also something accessible.
I want to share with you this experience, because, I had a good and an bad experience to share.
