By default you can only get the total battery voltage with Crossfire telemetry. Here’s an easy trick to get averaged cell voltage from telemetry, so you don’t have to do the math in your head.
In the latest OpenTX they added “model match” to Crossfire, i.e. RXNUM which is basically a number you can assign to a model before binding the receiver, this allows the model profile on your radio can only control a particular receiver.
The Crossfire Micro V1 was on sale at half price recently, some of us was right to guess they were preparing for the release of a new product – the Crossfire Micro TX V2 module. Let’s take a look at what’s new.
Multibind allows you to bind a receiver to multiple transmitter. For example, if you have the Micro TX V1, and you just bought the V2, you can setup multibind so you don’t have to go through binding all your quads to the new TX module.
The Mini Immortal T Antenna is now available for TBS Crossfire receivers. These antennas are super tiny and should be great for micro quads such as Tiny whoops and “Toothpicks”. Let’s compare its performance to the Immortal T V2.
Long range radio systems using 900MHz including the Frsky R9M and TBS Crossfire typically use a single dipole antenna on the receiver. The optimal antenna positioning can be different from traditional 2.4GHz systems with diversity monopole antennas on the receivers.
You might wonder, “isn’t Crossfire faster than SBUS? Why would you still want to use it?” Well yes, you should use CRSF over SBUS whenever possible. Crossfire requires both RX and TX pins of a UART while SBUS only needs the RX pin. When you don’t have a spare UART that then your next option would be using SBUS.
