Sub-GHz

Frequencies

Document image


Flipper Zeros sub-1 GHz module is capable of receiving signals at all frequencies in the 300-348 MHz, 387-464 MHz, and 779-928 MHz operational bands. However, Flipper Zero transmits signals only at frequencies that are allowed for civilian use.

On this page, youll learn more about how signal transmission works in your Flipper Zero, and find a list of frequencies allowed for civilian use in particular regions.



How to determine your region and allowed frequencies

Flipper Zero has the send function disabled out of the box until the device is updated either via Flipper Mobile App or qFlipper with a microSD card inserted. If you try to use the Sub-GHz function before updating Flipper Zero, you will see the following message: Firmware update needed. Update the firmware before using this feature flipp.dev/upd.

While updating Flipper Zero, the region where the device is located is determined and frequencies allowed for transmission in that region are unlocked. To see your region code in the ISO format while on the Desktop, press and hold the %down%DOWN button.

On the Device Info screen, you can see your region code in the ISO format
