A quick overview of the CC1350 Sensortag development boards that arrived today. I must say they pack a lot of capability into a very small package (42x32x5mm), at a affordable price.

On board:

• TMP007 IR thermopile and ambient temperature sensor
• OPT3001 Ambient light sensor
• HDC1000 Humidity sensor
• BMP280 barometric pressure sensor
• MPU-9250 Accelerometer, gyroscope and compass
• MK24 reed switch
• SPH0641LM4H-1 microphone
• ON board antennas for both the BLE and Sub-Ghz radio, as well as connectors for external antennas
• 2 buttons
• Coin cell battery holder

Connecting the sensors to my smartphone is as simple as downloading the TI app, pulling out the battery tab.

The boards also come with nice little enclosures. In the photo the module on the right has the Debug-DevPack added on top of it, which breaks out the remaining pins to a 1mm pitch header as well as some pads for grove sensors. It is also required to do firmware programming and debugging. It connects to the sensor tag via a hermaphroditic "SKIN connector". All the design files are available on the TI website, so designing my own DevPack to connect the other sensor I require should be relatively simple. I was able to get some free samples of the SKIN connectors which I will use for this purpose.

The board is actually the perfect size for testing as a ear tag. So the plan is to make a DevPack with the other sensor I require and make a enclosure that would allow use as a ear tag or collar. The GPS will add a bit to the size, and eat the coin cell for breakfast, but it should be enough for some quick testing. In short I believe this dev kit will be extremely handy for both this project and my FireBreakNet project.
