PortaPack Versions - posssss/portapack-mayhem GitHub Wiki

There are many different versions of PortaPack, mainly due to Chinese’s 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.

The current list is:

Version	Compatible	Screen size	AK4951 Codec	WM8731 SSOP Codec	WM8731L QFN Codec	CPLD	INS 8002E Audio amp	LTK 8002D Audio amp	CS 8122S Audio amp

(Note: The H3 is Incompatible, do not buy it as it's a scam)

H1(R1/R2)

Differences:

• The H1R1 has a WM8731 audio chip
• The H1R2 has a AK4951 audio chip
• Some versions have a touch screen while a lot of the clones do not

H2

Differences:

• Bigger touch screen
• Different control/button layout
• Built in battery

H2 (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 (speaker output may be shorted 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.

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.).
