Servo-RDT is a lightweight (1.1g) RDT/timer solution with a dedicated servo output.
The battery input uses a JST 1.25mm connector, so you can plug in a compatible battery without soldering. If you prefer a smaller footprint, you can remove the connector and solder directly to the larger pads underneath — ideal if you have a fine-tip soldering iron.
The onboard receiver is compatible with all BMK transmitters, including B1, B2, FlexiDisplay, and Skylink. You can pair a transmitter with an unlimited number of receivers thanks to each unit’s unique transmission code.
Removable JST Sockets
These Micro JST 1.25mm sockets offer plug-and-play use.
Alternatively, the JST socket can be removed and wires soldered directly to onboard pads for a robust and low-resistance connection
