Introduction

PortaPack is an add-on for the HackRF Software Defined Radio (SDR) platform that adds a touchscreen display, buttons, and additional functionality to transform it into a portable SDR device. There are many versions of PortaPack available on the market, created by different manufacturers, often with varying features such as larger screens, added charging capabilities, or different main chips due to price and availability.

This guide provides an overview of various PortaPack versions, their compatibility with Mayhem, and key differences between models. Please ensure you verify hardware compatibility with the vendor before purchasing, as manufacturers frequently change components without notice.

Portapack Versions Comparison

There are many different versions of PortaPack, mainly due to Chinese companies putting their own take of the design such as adding a larger screen, adding charging or changing the main chip due to price and availability.

Most manufactures changes components frequently without notifying anyone, thus you should always ask the vendor the compatibility of their hardware before you buy, even if a specific vendor/store/seller already has a lot of positive reviews.

Asking which one to buy in the community is welcomed, however it could be not helping since things changing fast and no one can guarantee you that something will be 100% working.

The current list is:

[!NOTE]

• Any versions of H3 are incompatible (we will never do support of this hardware), do not buy them as they're scam.
• "H2+" and "H2 Plus" are different devices, even if their names sounds similar.

• This usually comes with a new crystal clear case so you can see all the beautiful silkscreen art.
• Comes with a built in microphone.
• Has new CPLD code so the reboot button doesn't freeze the device unlike some of the other H2's on the market.

H2 (old OpenSourceSDRLab version)

Differences:

• AK4951 with 3W CS8122S Amplifier chip (INS8002e clone) -- speaker shuts off automatically when headphones plugged in
• NOTE: Do not enable AK4951 Speaker Output icon on title bar on this model or the AK4951 IC may overheat (CS8122S and AK4951 speaker outputs seem to be tied together on PCB)

H2+ R1

Differences:

• Similar to H2 in early versions except claim for better TXCO spec(questionable) and board marked as H2+.
• Battery state indicator with 4 leds under Encoder Knob for 25%,50%,75%,100%,flashing while charging, steady when that level full.

H2+ R2

Differences:

• Similar to H2+R1 except using the WM8731 Codec and has an added audio power amp INS8002E. The front face of the board is marked as H2+ as in H2+R1 above.

H2+ R3

Differences

• Similar to H2+R2 except
• This versions the standard CPLD 5M40ZE64CN5 was replaced with EPM240T100C5N ( due to cost and supply issues by supplier "OpenSourceSDR Lab") which has caused some issues ( they issued their work around fixes in a version 1.4.3) and resolved in version 1.5.x due to a lot of hard work.

H2+ R4

Differences

• Similar to the H2+R3 except it now uses the AG256SL100 IC as well as the 28 pin QFN WM8731L instead of the 38 pin QFN AK4951. Marked as "PCB v3.6 mmdvm.club".
• 3W LTK8002D SOP8 Class D amplifier for the speaker (INS8002e clone).
• Power IC IP5306 SOP8.
• Inserting headphone plug doesn't disable the speaker.

H2+ R5

Bascially H2 with internal microphone and a independent power switch (but only pad/hole exist in some of the boards.)
Community reported it works (including the internal microphone), but other infomation are unknown.

H3

Uses custom close source firmware. Not compatible with Mayhem. Do not buy or support as it's a scam

This also exists as H2 Plus. Uses custom close source firmware (Ref.). **Not compatible with Mayhem(Ref.).

(NEW) H4M (Mayhem Edition)

[!TIP] Click the images to see them on their full glory

Differences:

• 🔌 GPIO port! The H4M adds a GPIO port so users can make their own add-ons for the H4M, just like the flipper.
• 🔋 Advanced battery management IC (battery %, voltage, current/draw, etc...)
• 🕹️ Single power on/off switch.
• 🚫 When powered off, the battery will no longer phantom drain.
• 📱 flat design, going back to the iPod style click wheel. (so no more broken buttons and encoders!)
• ⚡ Improved charge speeds.
• 🎙️ Built in mic (and mic switch between internal and external).
• 🖥️ Matte screen.
• 💎 This usually comes with a new crystal clear case so you can see all the beautiful silkscreen art.
