EHS5/6/8 Eval Board Schematic | Telit Cinterion IoT Developer Community

Hello,
i've a DBS75 with Multi-Adapter R1 and a BGS5 on a EHS5/6/8 Eval board.
I also have the schematics for the DBS75 and the Multi-Adapter but not for the EHS5/6/8 Eval board.
As i want to use I2C i need access to the 1.8V voltage output of the BGS5 (for the required pullups) and SDA/SCK which do not seem to be routed to the GPIO header of the Multi-Adapter.
Therefor the schematics of the EHS5/6/8 Eval Board would be extremely useful.
Please advise,
Ralf
Hello,
Multi-Adapter R1 may not have all interfaces available. AH6 adapter is better here.
I can see in the multi-adapter documents that i2c lines are not routed to DSB75 but there's a note that they can be accessed through solder jumpers. However I can see that I2CCLK and I2CDAT are marked on the adapter's connector.
At the moment I don't have the eval board schematic but you can find all the module's pins (that are soldered to the adapter) in the BGS5 Hardware Interface Description which you can download here: https://iot-developer.thalesgroup.com/documentation/bgs5-technical-docum...
If this is not helpful I will be able to provide you more help on Monday.
Best regards,

Hello,
thanks for your reply. Unfortunately the hardware interface description is only of little help as i need to know which lines are actually connected and which are not, so it would be great if you could supply me with the schematics of the EHS5/6/8 Eval Board.
Best reagrds,

Hello,
I'm sorry but I've got the information that this document is not public. I don't have access to it and even if I had I couldn't share it with you.
All lines of the module must be connected to the EHS5/6/8 Eval Board's connector and via this connector to the adapter. So if they are not available on the adapter and connected to the DSB75 you need to use other adapter type or you can solder to these lines on the EHS5/6/8 Eval Board to module connector.
Regards,
Bartłomiej
