NRF24 & CC1101 433Mhz For M5Stack Cardputer ADV, Auto Switching, Strong Signal, Bruce Compatible PINGEQUA Hydra RF 424 Module

A Smarter 2-in-1 RF Solution for Cardputer ADV

Made for Cardputer ADV + Bruce (Setup Required) Designed specifically for M5Stack Cardputer ADV with Bruce firmware. Please configure brucepins.conf before use and reboot to apply settings. Not compatible with Cardputer V1.1 or other non-ADV/older models.

Enhanced Power Stability for Better Performance Consistency Built with ME6211 low-noise regulation + 100µF tantalum energy storage to improve transient current handling and voltage stability, helping the module maintain more consistent behavior under high-load scenarios and reducing issues caused by power fluctuations.

Auto Switching Convenience — No Manual Toggle Needed Integrated mutual-exclusion / switching control logic optimized for Bruce workflows. No physical switch needed for manual switching, reducing re-plugging and repeated reconnect steps for a smoother day-to-day experience.

SPI/GPIO Protection — Better Host Interface Safety Protection design applied to SPI and key control lines (current limiting / isolation / biasing concepts) to enhance fault tolerance and help reduce the risk of host interface damage from mis-operations or abnormal states.

Signal-Enhanced Design with Optimized RF/Antenna Path Optimized RF routing and connection consistency (layout/return path/connection details) to improve stability and consistency for a stronger, more reliable feel in real use. Actual results vary by environment and antenna setup.
