Frequently asked questions
Do I need to create an account?
No. There is no account and no sign-in, and the apps make no network calls at all — not even for remote codes, which ship inside the app. Remotes, captured signals, and device state never leave your phone.
What boards are supported?
One board: a 433 MHz radio and infrared on a USB-C plug. It is not for sale yet — it is headed for radio certification. See the device.
Do I need to install any drivers?
No. The board speaks class-compliant USB-MIDI, so iPhone and Android both see it the moment it is plugged in — no MFi chip, no driver, no Bluetooth pairing, no adapter.
How do firmware updates work?
Through the STM32 ROM bootloader, from the web flasher on a desktop or an Android phone. iOS cannot flash: there is no room on this part for a bootloader of our own, so updates go through the ROM one and are destructive.
Where can I get help?
Start with the documentation, which covers setup, the five screens, and firmware updates. For bug reports and anything the docs do not answer, use the contact address at the bottom of this page.
