Brand: BetaFPVSKU 16490BetaFPV have released a new version of the ELRS Micro TX transmitter module with a maximum output power of 1W. This module comes in a black case and runs on the new BetaFPV ELRS V2.0.0 firmware version, which supports full display and 5D joystick operation. A new Backpack feature has been added, allowing wireless communication between the ExpressLRS and other FPV devices, such as video goggles, for control and monitoring or to request configuration.
Compared to the 500mW versions, this module not only includes a cooling fan but also a heatsink, which improves cooling efficiency. Thus, this module can operate at 1W without overheating.
Note: make sure the video receiver also supports the Backpack function when using the VRX-Backpack module function. Backpack function will be added to the 500mW version in the future.
The BetaFPV ELRS Micro TX module is compatible with radio equipment that has a Micro (JR) type module bay, such as the Frsky Taranis X9D, Taranis QX7 A, TBS Mambo, RadioMaster TX16S, Jumper T16 and others.
Below is the schematic for the BetaFPV version of the ELRS Micro TX 2.4G 1W ELRS. DIP switches will be added to the 500mW versions in the future.
Note:
BetaFPV Micro TX Module ELRS V2.0.0 firmware has been released, and the firmware does not include Binding Phrase. Therefore, please make sure that the receiver is running the official protocol version V2.0.0 or higher and does not have Binding Phrase set.
BetaFPV ELRS V2.0.0 firmware includes features such as:
You can use the official ELRS firmware V2.1.0 or higher, which also supports all of the above functions.
Below is the basic layout of the 5D joystick and OLED buttons for BetaFPV ELRS V2.0.0 firmware.
Note:
ExpressLRS uses the Crossfire serial protocol (also known as the CRSF protocol) to communicate between the radio transmitter and the TX module. Therefore, make sure that your radio transmitter supports the CRSF serial protocol. This example uses a radio transmitter with an OpenTX system to show how to configure the CRSF protocol and LUA script. To configure this, on an OpenTX system, go into the model settings and on the "MODEL SETUP" tab, disable "Internal RF". Then enable "External RF" and select "CRSF" as the protocol.
ExpressLRS uses the OpenTX LUA script to control the TX module, such as binding or tuning.
The BetaFPV Micro RF TX 1W module is shipped with the official ELRS protocol of the main version V2.0.0 and without the mandatory Binding phrase. Therefore, make sure that the receiver is running the official ELRS V2.0.0. protocol and that no binding phrase is installed in the receiver. The BetaFPV Micro RF TX 1W module can enter the binding status via the ELRSV2.lua script as described in the "LUA script" chapter. In V2.0.0, enter the BIND state by short pressing the 5D joystick, then the RF module will enter the binding status.
Note. The LED will NOT blink when the module enters the Bind status. The module will automatically exit the Bind status after 5 seconds.
If you are re-flashing the RF TX module firmware with your own bind phrase, make sure that the receiver has the same bind phrase. In this situation, the RF TX module and receiver will communicate automatically.
The Micro RF TX module can switch the output power via the ELRSV2.lua script as described in the manual in the "Script LUA" chapter. Alternatively, use the joystick button and OLED display to move to the "Output" position and switch the power by pressing the button left or right.
Note: the RGB LED will NOT change depending on the output power. When the output power is 250mW or higher, the fan will rotate automatically.

Флаймод, без обид.
Модули NANO, да нужно вскрывать что б прошить, и то только V1, и то есть инструкция куда, что допаять что б не нужно было разбирать и нажимать кнопку.
