CC2541DK-MINI: IMU with Bluetooth & IR

RK Hiser

Part Number: CC2541DK-MINI
Other Parts Discussed in Thread: CC2541, CC2540, CC2340R5

Hi TI Team,

I'm trying to find the right part number/SDK for an IMU that can support both bluetooth and IR.

Thanks-

    Hello RK Hiser,

    Here is a picture from SmartRF Studio 7 which shows our CC25xx devices and which protocols they support:

    The CC2541 (non USB), CC2540 (usb) should be good options for BLE, however I do want to ask if there was any specific reason to lean towards using the CC25xx device compared to our newer CC23xx devices?

    IMU

    Do you mean inertial measurement unit? or some other acronym. Both the CC2541 and CC2540 are MCUs. 

    Thanks,

    Hi Alex,

    Thanks for your help. I haven't looked into the CC23XX devices and appreciate your guidance. Apologies for the alphabet soup- yes, you are correct. I was referring to an inertial measurement. Hopes are to find one (IMU) that supports both a Bluetooth and an IR interface or one that could be integrated in a small form factor and that has an accompanying SDK. Thanks.

    Hello RK Hiser,

    Assuming both the IMU and the IR interface need an I2C sensor you would need a device that supports two I2C interfaces (unless you want to use some addressing in that case one I2C could be used). 

    Neither the CC2540 or CC2541 have I2C so I cannot recommend them for your IMU and IR use case.

    So I would recommend the CC2340R5 as it does include an I2C interface and supports Bluetooth as well as having other useful factors (low power, easier to code on than the CC25, etc).

    Thanks,
