BetaFPV Micro RF TX Transmitter Case (White)

BetaFPV Micro RF TX Case (White)

The BetaFPV Micro RF TX Case (White) is a practical and stylish housing designed for hobbyists building or refreshing their own ELRS Micro TX module. This updated Micro JR bay case features an improved design and a USB Type-C port opening sized to fit most commonly used cables, making daily setup and use much more convenient.

Built for makers, FPV pilots, and ExpressLRS enthusiasts, this case is sold separately from the cooling fan, giving you the freedom to configure your module the way you want. If you're putting together a custom transmitter module, this shell is a great foundation for a clean, durable build.

Key Features

Cooling Fan Performance

Thermal testing shows that the cooling fan plays an important role in keeping the ELRS Micro module working within safe temperature levels. At a maximum RF output of 500 mW over 30 minutes of operation, the RF chip temperature stays below 50°C, while the outer case remains around 30°C. This makes it well suited for normal day-to-day use without major overheating concerns.

For the black version, which supports up to 1 W, tests with a heatsink showed temperatures staying below 65°C. Testing also showed that the RGB LED temperature can rise by around 10°C in both the 500 mW and 1 W versions, which is why the cooling fan is considered an important part of the setup.

Users often ask whether the fan should blow air inward or outward. According to the test results, the only noticeable temperature difference appears on the JR case itself, while the internal electronic components are not significantly affected by airflow direction.
