Hijacking I2C interface via test points on Thingy:91

[molviken]

Hi! 

I am currently working on a project where i would like to use Thingy:91 as MCU board as it contains other features i need to use, like 4G and GPS. 

The problem is that I need to to communicate with a 9-axis IMU to calculate angle and orientation of device. In addition, the device needs to be able to be able to at least have 2 analog inputs (SPARE2 and SPARE 6 should work for that). 

I was wondering if there is a possibility in "hijacking" one SDA and SCL line from two test points (TP9 and TP10)?

Hi,

 

Here's a thread on this matter:

As a generic note, we recommend that you use the nRF9160-DK as a basis for a development platform due to ease of access to GPIOs.

 

Kind regards,

Håkon
