## Key Observations

### Best Value Standalone
- **Potensic RID-916** and **Holy Stone HSRID03** at ~$30-35 are the cheapest standalone options with built-in GPS and battery. BT-only, FAA-only compliance.

### Best for FPV
- **Phoenix UAS mRID** (2.2g, $69) and **BlueMark DB153fpv** (2g, EUR 59) are the lightest options. Both need external GPS.
- **Lumenier RID** ($20, 9g) is the best value with built-in GPS and GPS passthrough to FC.

### Best for Open Source / Custom Builds
- **Holybro Remote ID** ($25) running ArduRemoteID is the cheapest path to open source RID with BT+WiFi.
- DIY ESP32-C3/S3 dev board ($5-10) with ArduRemoteID firmware is the absolute cheapest but requires ArduPilot FC.

### Best Multi-Region Compliance
- **BlueMark DB120/DB150** and **Dronetag Beacon V2** cover both FAA and EU.
- **Dronetag Mini** covers FAA, EU, UK, and Singapore.

### Government/Defense
- **Pierce Aerospace B1** is the only Blue UAS Framework approved module.

### Modules NOT Found
- **BrainFPV**: Does not appear to make a standalone Remote ID module. Their RADIX FC may support RID via ArduPilot + external module.
- **Flywoo**: No dedicated Remote ID module found.
- **iFlight / EACHINE**: No dedicated Remote ID modules found. These manufacturers focus on FPV hardware (FCs, ESCs, frames).

### Japan
- Japan has its own RID system separate from FAA/EU standards. DJI provides firmware-based RID for Japan-market drones. Dronetag has announced plans to enter the Japanese market. Most FAA/EU modules are NOT directly compatible with Japanese RID requirements.
