Request schematic on SEN0463 - Gravity: Geiger Counter Module Ionizing Radiation Detector

Hi DFRobot Team and Community.
 

I am currently working with the Gravity: Geiger Counter Module (SEN0463) and would like to request the official schematic for this module.
 

I have noticed that DFRobot provides schematics for many other Gravity modules in their respective Wikis, but I haven't been able to find one for the SEN0463 yet.

Having the schematic would be a huge help for my project, as I need to understand the circuit layout better—especially regarding the high-voltage section and signal processing. 

I have already tried reaching out via email but haven't received a response yet, so I’m hoping you can help me out here in the forum.
 

Thank you in advance!
 

Best regards,
Nicolai J. Andersen
