Micro TX V2 Module--User Manual
ExpressLRS is a new generation of open-source wireless remote control system, dedicated to
providing the best wireless link for FPV Racing. It is based on the fantastic
Semtech SX127x/SX1280 LoRa hardware combined with Espressif or STM32 processor, with
characteristics such as long remote control distance, stable connection, low latency, high refresh
rate, and flexible configuration.
BETAFPV Micro TX V2 Module is a high-performance wireless remote control product based on
ExpressLRS V3.3, with strong anti-interference performance and stable signal link. It improves its
RF transmission power to 2W based on the previous Micro RF TX Module, and redesigns the heat
dissipation structure. All the updates make the Micro TX V2 Module get better performance and
more suitable for applications such as racing, long-range flights, and aerial photography, which
require high signal stability and low latency.

  • Page 3: Indicator Status

    Note: Please DO NOT use 6S or above battery to power up the TX module. Otherwise, the power supply chip in the TX module will be damaged permanently. BETAFPV Micro TX V2 Module is compatible with all the radio transmitter which has the Micro module bay (AKA JR bay, SLIM bay) Indicator Status Receiver Indicator Status Includes: Indicator Color Status Indicating Rainbow Fade Effect Power On Green...

  • Page 4: Transmitter Configuration

    Lora mode, with a remote control distance equivalent to 200Hz. Transmitter Configuration The Micro TX V2 Module defaults to receive signals in the Crossfire serial data protocol (CRSF), so the TX module interface of the remote control needs to support CRSF signal output. Taking the EdgeTX remote control system as an example, the following explains how to configure the remote control to output CRSF signals and control the TX module using Lua scripts.
  • Page 5 ● Download the elrsV3.lua on BETAFPV official website or ExpressLRS configurator. ● Save the elrsV3.lua files onto the radio transmitter's SD Card in the Scripts/Tools folder; ● Press the "SYS" button or the "Menu" button on the EdgeTX system to access the "Tools"...
  • Page 6 Parameter Note BFPV Micro TX V2 Product Name, up to 15 characters. Drop ratio of the communication between radio control and the TX module. 0/200 i.e. the TX module received 200 packets and lost 0 packets. C: Connected. -: Unconnected.
  • Page 7 Button and OLED There is a 5D button on the Micro TX V2 module. Below is the basic operation of the button and OLED. Long Press: Unlock and enter the menu page, or apply current settings in the menu page. Up/Down: Move to the last/next row.
  • Page 8 Note: When the RF TX module enters WiFi Upgrade status, the button will be invalid. Please re- power the RF TX module after the firmware update via WiFi. Bind The Micro TX V2 Module comes with offical major release ExpressLRS V3.4.3 protocol and no Binding Phrase included. So please make sure the receiver works on offical major release ExpressLRS V3.0.0 protocol. And no Binding Phrase set.

  • Page 9: External Power

    External Power The power consumption of the Micro TX V2 Module when using a transmission power of 500mW or above is relatively high, which will shorten the usage time of the remote control. Users can connect an external battery to the TX module through the XT30 port. The usage method is shown in the following figure.
  • Page 10 Note: Please check the battery level before inserting the TX module to ensure that the battery is fully charged. Otherwise the TX module will be rebooted due to insufficient power supply, resulting in disconnection and loss of control. Q&A [Q1] Unable to enter LUA script. Possible reasons are as follows 1. The TX module is not well connected to the remote control, need to check whether the JR pin of the remote control and the TX module socket are in good contact; 2.
  • Page 11 firmware of the remote control, e.g., the EdgeTX needs to be V2.8.0 or above).
