Using the CC1101

The Mini CC1101 board works the same as the internal CC1101 in the Flipper Zero and uses the same Sub-GHz apps. The working frequency of the Mini CC1101 board is from 410MHz to 450MHz and the included antenna is tuned for 433MHz. Some third party firmware have extra apps for Sub-GHz. If you're interested, check out the section Setting up your Flipper Zero

If you want to receive and transmit to even longer distances, you can purchase a larger antenna. Make sure the antenna is tuned for 433MHz with a 50 Ohm impedance and uses an SMA Male connector as shown below. The Male connectors have a needle in the middle.
