Power plug and battery with 3rd wire? Is this a new version?

[samdaly]

We received a new batch of Thingy 52 enclosures... but the many of them have a third wire going into the battery. Why the change? How can we tell the versions apart? Is this going to be the new normal? 

What would be really helpful is to know the version number of the product with each spec. Also, where I can get them for the given spec?

Thank you.

Hi. 

I wasn't aware of any new release of the Thingy:52. I'll make a request internally to our developers about this. 

I just want to double check that it is the Thingy:52, and not the Thingy:91 you are working with here?

Best regards, 
Joakim

Any updates Joakim? We are blocked in our development here.

Hi. 

You are correct. There has been a change to the Thingy:52 HW. 

It doesn't seem that the new HW files has been released yet, but they should be soon. 

The third wire from the battery is connected to the PMIC ( U16 - XC6804A4E1). It is connected to the THIN pin of the PMIC, which we can see from the PMIC datasheet is the Temperature Detection.

Can you post a link to the connector that is used on the board now? Also, can you please tell me the two different version numbers for the board so we know what we are ordering? Also, can you give a little background on the reason for the change? Thanks for your help.

Hi. 

The connector is a 1.0 mm pitch connector (Part number: SM03B-SRSS-TB(LF)(SN) ). 

The new version of the Thingy:52 should be v.1.1.0. You should be able to see that on the sticker placed on the Thingy:52. 

I've forwarded the questions about the reason for the change to our developers, I'll get back to you with more information. 

Cheers,

The reason for the change is because we decided to change the battery on the Thingy:52. 

Before we had a battery without a thermistor (2 wire) and a thermistor on the PCB. Now we have a battery with thermistor (3 wire). 

The latest HW files should be available for download on our website soon.
