Videos / Pycom Pysense Quick Overview

In this guide we take a quick tour around the Pysense board by Pycom. It features a 3-axis accelerometer and sensors for light, temperature, humidity and barometric pressure.

G'day guys Chris again from core electronics. Today I'd like to show you the PySense shield for your PyCom microcontrollers. It's a lovely little device that gives you a lot of senses and you add it onto your microcontroller, so that you can build projects just directly from the sensors available in it. If you need a link to the documentation that's below the video here and we'll have a look at the bench and get started.

I've put on the bench here at our expansion board 2.0, which I've already covered if you haven't seen that there are videos for the overview and a getting started guide and next to it here we have the PySense from Pycom. So, the main difference obviously is the size the expansion board gives you a double row of pin headers here, so you can very easily put a bread board down next to it and while those across with jumpers.

The PySense doesn't give you the extra sockets which is a bit disappointing. Anyway, it's more designed to be a backpack that you put on your microcontroller and leave it there so that you can utilize these sensors.

So what does it got on it; at the top here obviously we have a micro USB socket and next to that is a JST socket for a battery, lithium ion/lithium polymer, next to that is all of the charging and power multiplexing circuitry, so you can change power sources around and the battery will charge whenever there's a secondary source, there's a little LED hiding in there that shows you that the battery is charging down, the right-hand side we have a user button, that is used as part of the BIOS flashing process on this board, there's also a sensor here for light, we just called the ambient lights, below that is very tiny is a humidity and temperature sensor, this metal package at the bottom is barometric pressure, obviously we have a usual micro SD slot, in the middle here we have a 10 pin breakout, that hasn't been populated, so you could solve the wrong socket there if you need to access some of the pins not all of them, in the center here is a three axis accelerometer and interestingly at the top here where the expansion board has and FTDI chip, this one has a pic microcontroller.

So, as I've already mentioned this board has its own firmware whereas the expansion board 2.0, is not a smart board this, one is an intelligent board with its own microcontroller and has its own software. I found that software updating process to be a bit difficult, so I documented that separately and will put up a video shortly.

All right, if we go over and have a look at the pc, I’ll show you some of the information that I've documented there.

So, here we are on the core electronics website if you go into the search box and just search Pycom and without even pressing enter you can run down to the bottom of the results in the search box to find where I've landed here. So, this this article is called Pycom PySense overview, the main points of this article at the top, there's a three-axis accelerometer, ambient light temperature and humidity and barometric pressure.

So, the features diagram here, shows us only what I already showed you, if we go down a little further I've documented a comparison between the expansion board and the two-other sense of backpacks that are available now. The main thing again is the accelerometer light sensor temperature and humidity and barometric pressure. At the bottom here is a pinup diagram where you can find the 10-pin header that is in the center of the board if you want to solder in a socket there you can access some of the iOS.

Of course, these things link off to more detailed documentation, so if I just click on the pinup diagram, there I've gone straight to the Pycom documentation to get the full diagram.

All right so now you've seen the PySense from Pycom. I think you'll find it a useful little board, when we do a getting started guide, will go through writing code for it and getting to use all those senses. So again, click the link at the bottom to get to the documentation, if you can like and share us around that'll be great.

So, thanks again, for watching core electronics.
