WICED Smart Bluetooth

Anonymous

I've tried to find the document that specify the type and voltage compatible with WICED Sense but none of them does specifically.

What I know is that CR2032 3.0v works. However, I want it to be rechargeable like LIR2032 but that will be 3.6v.

Anyone try LIR2032 before?

Will 3.6v damage WICED Sense?

Thanks,

WICED Sense leverages the BCM20737S SIP module.

Per the datasheet for the module: BCM20737S Bluetooth Low Energy SiP Module Technical Reference

The Max Supply Power is 3.63V.

I've test WICED Sense with a fully charged LIR2032 rechargeable battery.

My voltmeter tells that it is actually 4.1v (not 3.6v as written on the battery).

However, my WICED Sense works fine on that battery.

Often the open circuit voltage of a battery will be different from the in-circuit voltage. So a battery may test as 4.1v with nothing attached, but when it's in an actual circuit the voltage will drop to 3.6v. If it's still 4.1v in the circuit then get a new voltmeter or get a new battery.
