Expansion Interface
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
The common HackRF expansion interface consists of headers P20, P22, and P28. These headers are present on both HackRF Pro and HackRF One, and support hardware add-ons including PortaPack and Opera Cake.
|
|
|
|
P20 GPIO
|
|
^^^^^^^^
|
|
|
|
Providing access to GPIO, ADC, RTC, and power.
