I ordered a telemetry kit and it came with cables that seem incompatible with my Pixhawk 4 (JST-GH). Here are some pics:
The TELEM1 port connector on my Pixhawk is JST-GH. The stranger thing is that even the provided cables don’t seem to comfortably plug into the radio modules. I am afraid that I might break the pins if I push it in too hard.
What’s the easiest solution?
Aliexpress Droneblock.
All kinds of connectors (1.0, 1.25, 1.5, DF13, 2.54, Pix2, DF13…) and solid pre-crimped silicone cables in different lengths and ending combinations. For JST-GH I think you need Pix2; telemetry 1.25.
Excellent service.
All cheap. Order many, follow consistent cable colors, and triple check pinouts.
Buy a new cable.
Tried it. For some reason, the DF13 isn’t connecting properly either!
It turns out that it might be the JST-SH 1.0 connector that’s needed
