H4M and Transparent Shell Kit

H4M and Transparent Shell with speaker and 2500 mAh Lithium Battery.

The improvements of H4M:

• Single power on/off switch. When powered off, the battery will no longer phantom drain, i.e., the device can be completely powered off.
• Advanced battery management IC and battery display (battery %, voltage, current/draw, etc...). It is easier to check the battery level.
• Matte screen. This matte screen can help you see the content of the screen much more clearly in sunny places outside.
• 360-degree Knob Button. The knob button becomes to be the flat design, going back to the ipod style click wheel. The knob is more convenient to use.
• The GPIO port! This new generation H4M adds a GPIO port so users can make their own add-ons for the H4M, just like the flipper zero. This is a big step forward, and it's a design that hasn't been in any previous version of Portapack.
• Improved charge speeds. The H4M improves the charging quality and speed.
• Built in microphone and switch toggle. And there is a toggle to switch between the Built-in and the Headphone Microphone.
• Automatic switching of sound between the headphone and the speakers. Once you plug the headphone, the H4M will automatically switches from speaker mode to headset mode. This is also a feature that the previous Portapack did not have.

Note: Does include the HackRF One.
