USB receiver base — PRE-ORDER

Pre-orders still open! Bank transfer only (SEPA EUR or USD wire).

Short version - production isn't ordered yet, because paid pre-orders haven't reached the cost of a production batch. We have 200+ people on the waitlist since March, only ~40 pre-orders placed, about half of them paid. Once we hit the cost, we order within the week.

Why pre-orders at all: we're two people, assembling and shipping everything ourselves for 7+ years, through full-scale invasion and without access to global payment systems. Had to pay middlemen just to accept cards, and could only receive money after shipping. This only paid for small batches - last one sold out in two days. Pre-orders via bank transfer are the only solution to break the cycle without taking out loans we can't pay off.

You can join the waitlist here and get notified when the batch comes in stock - but in stock happens after production, production happens after funding. That's what works from here.

All our devices are open source - you can build them yourself, the designs are free and will always be. What you are paying for - assembly, calibration, testing, and the continued existence of people who publish those designs. We think it's a fair trade.

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.
