The new HackRF Portapack H4M fixes a bunch of issues in the previous versions. It now has a true on/off power button, that isn't accidentally pressed. It has real battery monitoring in the firmware and better charging through USB-C. As well as a built in speaker and microphone, better rotary encoder and buttons and completely new GPIO connections for future hardware expansions.
The HackRF Portapack H4M in this video has been sent to me for free by OpenSourceSDRLab. I’ve not received any payment for making this video and they haven’t seen it before I’ve published it.
