+This QuickStart guide aims to have you connected to the Android Direction Finding App as quickly as possible with the KrakenSDR running on a Raspberry Pi 4 or Orange Pi 5B (OPI5B) (the model with WiFi). However, please make sure you read the rest of the manual to understand how radio direction finding works.
 
 ## What you will need
 This guide assumes that you have the following equipment
 
 * KrakenSDR
-* Raspberry Pi 4
+* Raspberry Pi 4 or Orange Pi 5B
 * Antenna array (five identical whip antennas with five identical coax cables)
-* USA-A to USB-C data cable for Pi 4 to KrakenSDR data connection
-* USB-C power supplies for Pi 4 and KrakenSDR
+* USA-A to USB-C data cable for Pi 4 / OPI5B to KrakenSDR data connection
+* USB-C power supplies for Pi 4 / OPI5B and KrakenSDR
 
 It assumes that you will be mounting your antenna array on a vehicle for direction finding.

 # Burn SD Card Image
 
-The next step is to burn the KrakenSDR Direction Finding (DF) image to an SD Card. You will need an 8GB or larger card, and we recommend using class 10 or faster to ensure no file system slowdowns.

 2. The KrakenSDR will automatically have started processing. Ensure that the Connection Status, Sample Delay Sync and IQ Sync indicators are all green, or all turn green after a few seconds if you opened the page during calibration, and that the Frame Index is increasing.
 3. Set the desired center frequency, gain, antenna array radius configuration, and other settings like VFO bandwidth and squelch for the specific signal of interest. Make sure to apply the update by clicking on “Update Receiver Parameters” after changing the centre frequency or gain settings.
 4. Check the Spectrum screen to ensure that your signal is being received as expected.
