Electronic Brick 125Khz RFID Schematics (Seeed Studio)

Hi all,
can anyone supply me with the schematics of the module
Electronic Brick 125Khz RFID ?

I have the v0.9b an I need to redesign the board (another mechanic format).
Thank you !

This product is a external product, so we don’t have the schematic too. Sorry for that.
