3DR Pixhawk Mini. What receiver R9 mini or R9 mm

Hi, please for advice. I’m a complete beginner and I haven’t found much on google. I have a 3DR Pixhawk Mini. R9 mm has inverted with port while r9 mini has Sbus_in. nowhere can I find what’s appropriate for me.

Thank you for the “advice”. Do you think this connection will be okay? Thanks
