Using the HappyModel ES24TX Pro Micro ExpressLRS TX module is quite easy. First, make sure your radio transmitter has a Micro JR bay. Then, simply insert the module into it. Connect the power supply within the 5v - 10v range. Once connected, you're ready to use it for your radio - controlled devices.
When it comes to the antenna, attach the Happymodel 2.4GHz Moxon antenna that comes with the module for the best signal performance.
Here are some important things to note. Don't exceed the power supply voltage range of 5v - 10v, as it may damage the module. Avoid exposing the module to extreme temperatures or moisture.
For maintenance, keep the module clean. You can use a soft, dry cloth to wipe it gently. If you notice any dust inside the module, you can use compressed air to blow it out. And remember, if you have any issues, always refer to the official documentation or contact the manufacturer.
