USB receiver base — pre-order (ships late April)

Pre-orders open — ships in a month (estimated late April). The last batch sold out in a day with most people left on the waitlist. Pre-orders are bank transfer only (SEPA EUR or USD wire) — card payments via our current fulfillment setup only clear after the order ships, so we can't collect upfront that way. Bank transfer lets us fund a larger production run than we could otherwise, and guarantee a unit for everyone who orders. It's otherwise a normal online order with a late April ship date. Payment instructions are provided during checkout. If bank transfer doesn't work for you, no problem — you can join the waitlist here and get notified when the batch comes in stock as usual.

The USB receiver base is a radio dongle that plugs into your PC and receives wireless data from uMyo and uECG sensors — no phone, no WiFi bridge, no Android required. It connects to your PC via USB and communicates with sensors over radio (UF1 protocol), keeping the sensor fully wireless. Wired sensor connections introduce noise; uMyo and uECG are designed from the ground up to avoid that entirely.

This is the recommended setup for serious R&D: higher throughput than BLE, lower latency, multi-device support (star protocol, multiple sensors simultaneously), and works on Linux, Windows, and Mac. Also the only current option for iPhone users, since iOS BLE support is still in development.

Works with uMyo in base mode (green LED) and nRF24 mode (purple LED). Web workbench GUI support for base mode is coming soon — see the roadmap.
