Hello, looking for some guidance on whether or not the assembly MCBL-00064-1 is available for utilizing the Graupner G-16 receiver. I see the part number associated, but there is no link to purchase. Also is the inclusion of the VOXL2 IO board required?  Any advice is appreciated.

Yes, it is included in
MDK-M0065-1-01
MDK-M0065-1-02

Which are the VOXL 2 I/O kits with R/C cables

Thank you @Chad-Sweet. Have you seen any issues with connecting a graupner receiver output to pin11(uart rx) on J19? Just looking for RC input without taking up more space with the IO board, and due to specifics we cant use certain radios. I cant find too much data on if the receiver has an inverted signal like the FrSky does.
