Is it only me, or is Matek starting to build very good FPV hardware? I think everybody knows Matek's PDB. Matek F405 flight controller series is also very popular. But do you know Matek also started to build VTXes? I didn't and when a friend showed me this:
I almost knew I want one. Matek 5.8GHz 40CH VTX-HV is quite interesting design. It can be mounted above flight controller: M3 mounting holes are 30.5 apart. That's not all, it supports serial protocol (Tramp), can be powered from 5V rail or main LiPo (7-24V), has u.fl IPX connector, comes with small dipole antenna and SMA pigtail, has 3 power levels (25mW, 200mW and 500mW) and supports Raceband.
But the best feature are: 2 buttons and a set of LEDs. It really makes setup super easy. Press Button A to select function, press Button B to cycle options (power, band, channel). And current state is presented with LEDs. Cool. Not like with TBS Unify Pro where you have to count blinks!
Bangood stated it uses SmartAudio, but it is not true. It is ImmersionRC Tramp protocol. Thank you Andrey for pointing that out.
