ExpressLRS Micro TX V2 868Mhz Module + SuperP 14-channel Receiver

ExpressLRS Micro TX V2 Module 868Mhz + SuperP 14-channel receiver package

ExpressLRS 868Mhz Micro TX v2 transmitter module

This "Micro" format 868Mhz transmitter module can be installed on the back of any radio control equipped with a "Micro" or Graupner format slot.

The 868Mhz transmission system with ExpressLRS protocol enables signals to be transmitted even at some depth underwater. Our tests showed a control depth of around 1.15m in chlorinated water, and a little more in freshwater. This system is therefore a solution for any modeler wishing to pilot a radio-controlled submarine who doesn't own an FM radio.

The module features a display and a "5D" button for configuring module parameters. It includes an XT30 socket for an external power supply: depending on the transmitter's configured power, the transmitter module's electrical consumption may require it to be powered by a small battery 7.2-7.4v in order to limit consumption of the transmitter's main battery.

This module is a version 2 of the transmitter module, with several improvements in terms of features:

• Improved transmitting power.
• Increased fan speed.
• Improved transmitter component.
• Increased input voltage range (5-25v)

14-channel SuperP 866Mhz receiver.

This ExpressLRS 868Mhz receiver features 14 channels (14 PWM outputs). It features two T-shaped antennas that should be placed as far apart and as perpendicular to each other as possible to optimize reception.

Radio control compatibility:

This transmitter module can be installed on a radio control system with a slot for a “Micro” format transmitter module, such as the Fr-Sky X9D and Fr-Sky QX7 radios.

The radio control must be able to communicate with the transmitter module using the CRSF protocol. The module is best configured using a LUA script.

On OpenTX-based Fr-Sky radios, version 2.3.12 or higher is required.
