PortaPack H4M + HackRF All-in-one
Introduction
The PortaPack H4M+ HackRF is a high-precision, open-source hardware platform engineered for sophisticated radio frequency analysis and development. By integrating a 3.2-inch matte touchscreen interface with optimized Mayhem firmware, this unit transforms the traditional SDR hardware architecture into a fully autonomous, field-ready instrument. It is designed for researchers, engineers, and developers requiring a versatile, high-sensitivity tool across a wide 1MHz to 6GHz spectrum.
Engineering Highlights
- Standalone Operation: Built-in 3.2” touchscreen interface allows for complete signal analysis and data visualization without the overhead of external computer tethering.
- Hardware Precision: Built on the HackRF hardware revision with high-quality gold-plated circuitry for superior signal integrity and reduced environmental noise.
- Ready-to-Deploy Kit: A comprehensive development ecosystem including a high-gain 20dB LNA, a multi-antenna array for 1MHz–6GHz coverage, and a protective, field-durable enclosure.
- Advanced Utility Suite: Pre-configured for real-time applications.
NEW FEATURES:
- Added GPIO Port. For add-ons, extensions, and potential mods. This hasn't been in any previous version.
- Added Power Button. Turn on/off. It helps protect battery from phantom drain.
- 3.2 Inch Matte LCD Touch Screen. Direct app interaction and visual interface.
- A ratory encoder with push button. It helps navigate menus and adjust settings.
- Improved charge speeds.
NOTE: This product is an open-source development platform intended strictly for educational, learning, and authorized cybersecurity research purposes only. Please ensure all usage complies with local laws and regulations.
The H4M Advantages
The PortaPack H4M is the first fully integrated, all-in-one solution in the PortaPack series. Unlike earlier models, which faced challenges with usability, power efficiency, and overall performance, the H4M brings several improvements. It features a redesigned architecture that offers enhanced functionality, as well as the latest version of HackRF hardware and firmware—Rev 10.

1. Matte Screen
The upgraded matte-finish screen offers high visibility, ensuring clear readability even in bright outdoor conditions.
2. GPIO Ports
The addition of the GPIO port enables the connection of add-on accessories, shields, and sensors.
3. Redesigned Power System
The power system has been completely revamped to include:
- Unified Power On/Off Switch
- New Advanced battery management architecture
- Fast Charging via USB-C
- No power leakage or battery drain
4. Internal / External Mic + Speaker Toggle
The built-in sliding switch enables quick switching between the internal and external microphone/headphone inputs.
5. Redesigned navigation wheel
The new low-profile navigation wheel, combined with directional buttons, enables quicker navigation while minimizing the risk of damage when the device is not in use.
6. Integrated Microphone
The newly integrated on-board microphone enables the H4M to function as a complete voice transceiver.
