 Digikey and ate a fruit present That's right everyone's favorite segment ion MPI this week is TDK an infant sense Which is the sensor of sub brand of TDK? I think this is our first TDK MPI and TDK is known for their sensors So this is why I was really excited to see this MPI show up on digikey. It's the Smart bug so this is the smart bug multi-sensor wireless like dev board from TDK just came out and It's you know about 80 bucks and is like jam packed with sensors. This is a really cool board It's got an NRF 52 840 in it a battery a bunch of sensors and there's accessories So there's this like add-on board and this is kind of cool It has an SD card for data logging and there's like a built-in data logger capability There's a time-of-flight sensor. That's that little thing hanging off with the cable It plugs into the side I'll show that in second how it plugs in and on the back there's an ESP 32 module So you can actually add Wi-Fi connectivity as well. It comes to default with Bluetooth low energy That's what the NRF 52 840 does it processes the sensor data and then you know sent it to your computer or your device for analysis So the weird thing that's going on here is you know that the Nordic is great This Wi-Fi is great, but what's really cool is it's jam-packed with sensors So, you know, we've really been hammering home like sensors are slow-cost. They're available There's so many sensors available from every company and what we've noticed is that eventually these companies are like We want to showcase all of the different sensors that we have is no longer like a company just makes a megatometer Or they just make a humidity sensor. It's pretty common for companies to have a full range So here's the range the sensors that are inside the sensor bug so you've got a motion sensor that's a six-axis IMU and This is TDK specialty. They're really good at motion sensors and magnetometers. There's a pressure sensor So this is good for barometric pressure or HVAC systems There's that ultrasonic time-of-flight sensor. You can add on there's the temperature sensor built into the pressure sensor humidity sensor There's a magnetometer which senses magnetic fields and that's used with the motion sensor to perform IMU calculations where you do like a notional measurement or orientation measurement And of course, there's a humidity sensor as well. In fact one one that we really like the SHT series The humidity sensor, of course, can measure ambient humidity tell you if something is too damp or too dry So good for environmental sensing. So this is a nice range of sensors The actual sensors that are included in the parts are listed here. The ICM42688 Is a new IMU Like most TDK Invincent sensors this has built-in motion fusion algorithms So if you use their SDK you can actually do the sensor fusion on the chip and not on the microcontroller which saves you a lot of time because normally you have to like Get the data constantly and do the processing this way. It's done on the co-processor the IMU co-processor There's also the ICP-101 great name barometric pressure sensor The CH-101 is the at-time-of-flight range sensor the AK 09940 is the magnetic sensor That's used with the IMU for inertial measurement The SHT-C3 like we said, it's one of our favorite digital humidity and temperature sensors We have a breakout for that chip and then the main processor is one of our favorites the Nordic NRF 52840 and co-processor Wi-Fi with ESP32. It's actually kind of like it looks like an 8-bit board It's kind of something what we would design, right? We love the NRF 52840 and we're kind of hoping maybe somebody will port circuit Python to this board So the hardware is really good, but what's really great about this DevKit, which I liked is the software They did an excellent job on the software and this is rare The software is available on the Windows 10 app store, which is like the first time I think in a long time I've seen a development board evaluation software available on the Windows app store The reason this is nice is you don't get any weird warnings like what is the software you're installing? You don't have to worry about drivers It's like very nicely packaged and looks great and don't forget with Windows 10 You have native BLE support and that's how you're going to communicate with the smart bug So when you get the smart bug you can plug it in or power it on and then Just basically I just opened up the app. I said connect via BLE click pair and it just worked Which was magic. I didn't have to install any tool chains. I didn't have to like get into my shell prompt I didn't have to boot into like compatibility mode It just worked, which is really nice and there's a lot of great demos built into the software as well For example, they've got the classic plotter But hey, you know the plotter works really well and is great for testing all the sensors And you can see you can enable any sensor you like here I've just got the accelerometer and gyro you move it around you get data instantly you can change the filter parameters on the top right such as the data rate and You know the low pass or high pass filters and you can enable any sensors you like There's also a couple cool Application demos, which I thought was really smart. So, you know the the sensor data plotter is handy just for debugging But a lot of people are usually evaluating these sensors for a product So for example, let's say you're doing like a health monitoring product And you want to use the accelerometer that can do a pedometer activity logging and tracking Well, this demo called apex is does exactly that it's a pedometer demo and because it's wireless It's really nice. You just put the smart bug in your pocket and over be a little track your steps You know, I took a little bit of walk around the room and watched as the screen said, okay I detected that you're walking or you're sitting and then it also detect taps and double taps Another cool demo that I liked was this HVAC demo. So I didn't even think about it But yeah, like you could use the pressure sensor to tell you when your HVAC system filter needs to be replaced That's a really good idea because you'll otherwise you'll get poor efficiency in your HVAC system So this demo just shows here's how you can set Interrupts for different thresholds and then you know leds or or something can turn on to tell you or you can communicate with You know over Wi-Fi to an IoT service that'll email someone and say hey, you know filter number three needs to be replaced So that was a cool demo The thing that TDK InvinSense again, they're experts at is this IMU sensor fusion So of course their demo they have this cube that you can pick up the the bug and you rotate your hand and the Nine-axis orientation follows along and it's stable. It works great. There's very little jitter and there's very little Drift they've done a really good job and that you know, they give you the Euler angles here Check out the the TDK DMP processor, of course if you want to do sensor fusion on chip It's a very powerful capability that they have built into their micro their chips as a little micro controller inside And it's also why TDK InvinSense sensors are used for VR and gaming So, you know, if you remember the Nintendo Wii controller that used an InvinSense processor and the Oculus Rift Dev kit also used InvinSense for head tracking and hand-emotion tracking There's also a nice debug panel if you want to know a little bit more about the BLE Connectivity and you want to see, you know, what data is being read from what characteristics That's available. Just click on the debug panel. That's a little bug pun there Overall I really liked it. I thought this was a really cool little dev board I also thought it was really cute You know it goes far and a lot of boards are just kind of boring squares but I think they made something that was both adorable easy to hold and Fully functional and I thought I'd just show it on the overhead real fast so people can see so it comes With two pieces and I removed the screws and thank you for making the screws available and easy to find so when you remove the screws on top there is a LiPoly battery and here you've got the micro USB. It's kind of cool. It's got like an in-line micro USB It's nice and flat There's a lipo charger. There's the nrf 52 840. There's two LEDs These are at least by color because when you plug this into USB they turn green to indicate charging And blue to tell you it's in Bluetooth mode There's no on-off switch because it uses the accelerometer to know when there's no activity or motion It will go into power down mode. So since I've been moving it lately It's it's blinking and letting me know. Hey, we know that you're an active mode If I let this sit for half an hour, it'll automatically shut down to conserve battery power and then this is that expansion port So it looks like a 0.05 inch Header so you can use that to connect the Wi-Fi or time of flight Sensor and then over here. We've got all the sensors. So it looks like maybe this is the humidity sensor magnetometer barometric pressure and then this is maybe the accelerometer or maybe this is the accelerometer I'm not sure exactly So all the sensors on there a very nice cute little design some stuff on the back And then I really I like how that the LEDs kind of come out the eyes Yeah, all right design This is MPI and did you keys to place for the newest products? You could pick this up right now. They have a bunch in stock and they'll ship it to you tonight and The short URL did you key comm for it slash short for such z 5 j w 1 5 And you can also see the did you key? part number yes 14 and 2 md 4 2 6 8 8 p and e and That is this week's IMPI. Thank you everybody
