Some Frsky Devices with the Frequency 900

In this article we are going to talk about some of the models and some receivers that use the 900 Frsky frequency to perform long-range flights with our drones or our fpv wings. Next we are going to talk about some Frsky devices with the frequency 900.

Frsky R9M 2019 MODULE:

This module is compatible with all Frsky brand transmitters. It works at a frequency of 900 Mhz in its international FCC version and 868 Mhz in its European EU version. These devices in their international FCC version can operate at 4 different power levels that are 10mw / 100mW / 500mW / 1w. all can support telemetry .Smart port enabled for data transmission in telemetry

This device operates at a voltage of 6.5v to 13v. These devices incorporate a Smart port to update their firmware and also to transmit their data by telemetry

It has several antennas available apart from the linear format similar to the antenna of a Wi-Fi transmitter, it has a circular format antenna called super8 and then it has another antenna format which is the Moxon which is a pach format antenna

This tx module is compatible with accst and acces systems

The r9m module also has a reduced version called r9mlite that is compatible with the most modern and smaller stations such as the xlite / xlite station or the x9lite / x9lite s. It is curious that with a station of such small dimensions it is They can make flights of 5 and 10KM without any inconvenience. That is if we have to pay close attention to the placement of the antennas on our drone or on our fpv wing.

RECEIVERS COMPATIBLE WITH Frsky 900Mhz SYSTEM R9

• The R9 SX is the upgraded version of the R9 Slim series of receivers with long-range capabilities. Add 3-pin servo connectors with 6 full PWM channels and use dual antenna design. The lightweight protective housing has a 6-pin multipurpose plug to give you additional functions such as signal redundancy, telemetry feedback. Weight: 13g

 The 6 PWM channels can be converted into 4 PWM channels with the additional Ch5 and Ch6 being configured as S.Port and SBUS outputs alternative to the 6-pin port. The improved design proves to be more durable and together with the latest ACCESS firmware the two are now in sync and we can unlock the true potential of the ACCESS protocol.

• The R9 MX takes features from the earlier R9 Mini and R9 MM making it compatible with more external devices by providing a reversed S.Port output and supporting redundancy function. In addition, it retains solder points to connect 4 PWM channels. 

The improved design proves to be more durable and together with the latest ACCESS firmware the two are now in sync and we can unlock the true potential of the ACCESS protocol. Weight: 3.2g

• The 900MHz Mini-OTA R9 receiver implements the ACCESS protocol and provides the user with better performance and features. The R9 Mini-OTA supports wireless firmware updates over the air, making it even easier to connect with receivers. 

Plus the convenience of checking the current version of the receiver’s firmware. The compact form factor design of the R9 Mini is also carried over to the OTA version, and the R9 Mini-OTA also supports the redundancy function. Weight: 1.5g

• R9 STAB OTA receiver implements ACCESS protocol and provides user with enhanced performance and features. It supports over-the-air wireless firmware updates, making pairing with receivers even easier, as well as convenient checking of the current version of the receiver’s firmware.

Combined with a Frsky radio transmitter, the parameters can be conveniently adjusted via the LUA script. In addition, the parameters can also be adjusted using FreeLink (PC) and the FreeLink app (with AirLink S) .weight: 18.6g

• The 900MHz R9 Slim + OTA receiver implements the ACCESS protocol and supports over-the-air firmware updates, making it even easier to connect with receivers.

In addition to the convenience of checking the current version of the receiver’s firmware, the R9 Slim + OTA is designed with dual antennas to improve signal strength. 

Featuring a compact form factor design, it also features 6 PWM outputs, and this long-range receiver has the flexibility to work with more external devices by incorporating the inverted SBUS and S.Port outputs. Frsky Devices with the Frequency 900, did you find this article useful?
