I'm glad to hear! 🙂

Thank you!
I started off soldering onto the button. I've now tested using TP33 and TP32 on my desk-lab and it seems to work fine as well!

Received a response from a HW engineer: "There are not many unused GPIOs connected to the nRF91 on the Thingy:91. In addition to I2C, you can find SPI on a few test points. Also, P0.10 is not in use. You could connect this point via solder bridges to INT2 on the ADXL372 or 362.

In addition, two of the N-MOS gates are connected to a test point, since the drain & source are only connected to connectors, you can use these GPIO however you want to. You will get a bit more capacitance due to the transistors then."

Kind regards,
Øyvind

Hello,

Yes, according to the Thingy:91 documentation, there are extra GPIOs found on connectors P3-P6. Pin maps are found here.

Edit: According to HW schematics, P3-P5 are power connectors which leave P6 for GPIO.

Hope this helps your prototyping!

Kind regards,
Øyvind
