The Radiomaster Ranger Micro is a 2.4GHz ELRS module for JR bays. The ExpressLRS TX is a transmitter expansion module for standard radio bays. The module is compatible with radio transmitters running OpenTX or EdgeTX firmware. ExpressLRS (or ELRS) is an open-source project, and its transmitter and receiver modules are produced by various manufacturers, including Radiomaster. ELRS is currently one of the most advanced RC links.
It provides a reliable long-range connection, a high refresh rate of up to 1000Hz, adjustable power, Wi-Fi updates, and more. 2.4GHz ELRS outperforms conventional RC systems on the same frequency, while still using short antennas. ELRS has strong community support and is an open system that is evolving rapidly.
The Radiomaster Ranger delivers up to 1W of power and a refresh rate of up to 1000Hz. It features an omnidirectional antenna at the base of the transmitter for maximum coverage. This can be replaced with a directional Moxon antenna for greater efficiency, making it suitable for longer-range flights. The Ranger has a built-in fan to keep the module cool.
It supports Wi-Fi and Bluetooth connectivity, which simulator-flying enthusiasts will appreciate. The module also includes an ESP8258 for controlling ELRS Backpacks. The Radiomaster Ranger features a USB port for easy firmware updates and an XT30 port for connecting an external battery.
