"It comes out that it was too easy to be true. With GPS connected to Serial2 and MinimOSD connected to serial3, Mavlink heartbeat is sent to OSD and all onboard sensors (gyro, altimiter and magnetometer) data is passed onto MinimOSD. I have ran into…"

"Just to let you know, Serial3 is configured for MavLink by default and MinimOSD works perfectly fine without any code changes."

"Thanks Jean-Louis, from what I understand I need to get AIO to send Mavlink data through one of the serial ports to get the minimOSD working? Is there any documentation you can refer me to, so I can tune it? PS, I am just starting with Arduino, but…"

"Hi,
I am building an EasyStar/EG FPV platform. Is it possible to connect Crius AIO Pro to minimOSD using only one GPS module? Is there a telemetry output I can feed into OSD? Thanks."
