This board variant is based on the existing Tiny Relay implementation, with minimal hardware-specific adjustments. 🔧 Key differences / notes LED behavior Only the TX LED is actively supported and functional There is no available RX event hook in the current MainBoard interface, therefore RX activity cannot be indicated via LED Buttons GPIO pins for two buttons are defined However, they are currently not used in the firmware and have no assigned functionality TCXO configuration The following definition was required for stable operation: #define STM32WL_TCXO_VOLTAGE 1.6 Without this setting, the device consistently failed with error -707 The value may require further validation depending on hardware revision 📡 Testing The device has been tested in repeater mode, where it operates as expected Sensor and companion-specific tests were not performed, due to hardware limitations and the intended use case of this variant. This variant targets a low-cost and low-power hardware platform (Ebyte E77), making it suitable for simple repeater deployments where minimal hardware complexity and power consumption are required.

🔧 Key differences / notes
LED behavior
Only the TX LED is actively supported and functional There is no available RX event hook in the current MainBoard interface, therefore RX activity cannot be indicated via LED Buttons
GPIO pins for two buttons are defined
However, they are currently not used in the firmware and have no assigned functionality TCXO configuration
The following definition was required for stable operation:
#define STM32WL_TCXO_VOLTAGE 1.6Without this setting, the device consistently failed with error -707 The value may require further validation depending on hardware revision 📡 Testing
The device has been tested in repeater mode, where it operates as expected Sensor and companion-specific tests were not performed, due to hardware limitations and the intended use case of this variant.
