RadioMaster ExpressLRS USB UART Firmware Flashing Dongle V2

No second supplier matched for this listing — RaceDayQuads is the only route we can offer today. 6 of our suppliers carry RadioMaster, though, so it may be listed elsewhere under a different product name: GetFPV, NewBeeDrone, Pyrodrone, ReadyMadeRC, Rotor Riot.

RaceDayQuads: usually ships same day. Its shipping policy says: “Unless otherwise indicated, orders received prior to 4 pm with payment received will usually ship that day, unless it is a holiday or non-business day.” Policy, read 8 Oct 2026. That is the supplier’s dispatch time, not a delivery date; carrier transit is extra.
