Multiple questions: single Click shield? Adding supplemental power? Quickest way to see supported Click boards?

I think the Lin Hall Click board can be modified using a split ferrite toroid to act as a current sensor. Depends if the sensor is similar to the SS49E. A 3 bay adapter makes it unnecessarily "klunky". If just SPI interconnects and voltage a simple board should do it - is there one, like for the Raspberry Pi?

What is the quickest way to see if this and other Click boards are supported in Studio - someone warned me that some are not supported. Another way is to use a DAC Click board and have the current probe separate.

How do I judge the battery life for something like this? Is there somewhere to just add an external battery so no worries? For a data-logging app this thing would be running at least overnight.

Hi Barry,

'What is the quickest way to see if this and other Click boards are supported in Studio'

Just look at the available click in the studio: create a blank project, click on 'add element' bottom right and you will see already available ones. The one you consider is not supported for now.
We will release the ability to create any element in the tool likely end next week (is Under test right now). You will then be able to create your own element corresponding to whatever click you might want to use

How do I judge the battery life for something like this? Is there a way to add external battery ?

Depending on your project you shall be able to compute back an approximate. Here some orders of magnitude:
- Battery in the kit is 200mAh
- K64: about 30mA if left in default condition (always on, Max clock frequency)
- Sensors are by default on, most are not consuming much power except CCS811: roughly 15mA. If not used, this one must be definitely turned off.
- KW41: depends on BLE activity, but typically below 10mA
- Display: <<1mA, but display backlight; 15mA. Also do note that memory accesses are consumer a lot of peak power...
You can certainly have a rough estimate of the current consumption for your sensors / ADC
If you want to make your life easy you can plug a power bank on the USB port. During prototyping phase this should be ok

If just SPI interconnects and voltage a simple board should do it - is there one, like for the Raspberry Pi?

MikroE released a board allowing to plug a single click and which is power with AAA bateries. Maybe is what you are looking for
