Upgrade your ELRS firmware with ease using our simple and effective tool. The new V2 version features a USB-C interface, enabling you to connect the tool to your PC via cable. The new power button allows effortless power cycling with a single press, eliminating the need to struggle with cables while holding down buttons. Our streamlined design makes preparing your receiver for a firmware update faster, easier, and more efficient than ever! When it comes to updating your ELRS receivers, you’re faced with two options: Wi-Fi or Serial Port. While Wi-Fi upgrading may seem convenient, it can be unreliable due to network instability. This can result in a bad flash, requiring recovery with a UART tool. That’s where the V2 ExpressLRS USB UART Flasher comes in, offering a reliable and easy solution for your firmware upgrade needs. With the RadioMaster V2 ExpressLRS USB UART Flasher, your wireless connection won’t be a concern. This dongle is specifically designed for ELRS receiver serial port upgrades, providing a reliable and easy solution for flashing or recovering receivers with a bad flash. Our USB flashing tool is a versatile solution, not limited to ELRS serial port upgrades. It comes with a range of connection options, allowing easy connection to our entire range of receivers. By switching between 3.3v and 5v, it can also be used for other devices requiring a UART interface. This versatility makes it a valuable addition to your toolkit, catering to all your firmware upgrade needs.
