Good things do come in small packages. Like FrSky’s latest flight controller. With a built-in R-XSR receiver and 20mm x 20mm mounting holes makes it perfect for a clutter-free micro quadcopter build. The RXSRF3OM is Betaflight OSD integrated and Smart Port enabled, which means it supports full telemetry.
Whats great about this board is you get an R-XSR receiver module built-in to the F3 flight controller, saving money, while also saving time having to wire and configure them separately.
