Technical Support & User Guide

The Most Smart, Stable and Powerful RF Upgrade for Cardputer

Hydra-RF is not just another expansion board; it is a re-engineered solution. We tackled the Cardputer's power limitations to prevent brownouts. We optimized the circuit with impedance matching to deliver superior range that outperforms standard modules. With its smart auto-switching design, you get a seamless, professional experience without hardware conflicts.

Highlights:

• Stable: Optimized Power and Antenna Degisn. 

• Powerful: Extended range for both Sub-GHz and 2.4GHz.

• Smart: Auto-switching logic for a better user experience.

1. Menu: RF → CONFIG → RF MODULE → CC1101

For NRF24 (2.4 GHz):
 
1. When Mode choose, select SPI Mode

⚠️ Note on Auto-Reboot

Due to the Cardputer's shared SPI bus design, heavy data traffic during 'Record Raw' may cause congestion and reboots. 

This is a widely reported issue in the community. Opera

ting without an SD card Helps. 

This is a hardware limitation of the device, not a module defect.
