On-device reactions
Oneira's expressive reactions run on the device, so its face can respond without relying on a cloud request.

For makers searching for an AI device with GPIO: what GPIO, I2C, SPI, and UART do in plain language, and how Oneira ships hardware tools on all four.
Product status
Working today means the expressive face has been demonstrated on a real Oneira device.
Connected beta features require the Oneira app, internet access, a compatible service, and permissions you approve. They can change and may not work with every service.
The short answer

Oneira Dream Big+
Small enough to look playful. Built with a dual AI chip, OLED screen, and 1K camera, plus optional connected experiences you control.
Each $80 Founding Unit includes one Oneira device with a dual AI chip, OLED screen, and 1K camera, plus the selected color and included eye set. Only the final 1K camera module may change before fulfillment. Optional connected services, separate accounts, usage, and third-party fees are not included.

See included hardwareOptional compatible connected services can extend Oneira when you choose. Setup, permissions, internet access, service terms, accounts, usage, and fees remain separate. Connected experiences work only with compatible services the owner deliberately configures. Oneira does not connect automatically to every service.

Understand the agent pathPlain language
GPIO means general-purpose input/output: simple on/off pins that can listen to a switch or drive an LED or relay. It is the first bus every maker touches, because one pin and one LED produce one visible result.
I2C is a two-wire bus that many small sensors share at once, each at its own address. SPI is a faster short-range bus that trades extra wires for speed, common for displays and memory. UART is classic serial — two devices talking over two wires, one line in each direction.
On Oneira
Oneira ships hardware tools on GPIO, I2C, SPI, and UART today — the buses most hobby electronics already speak. That places an AI pocket companion in the same conversations as the sensors, displays, and boards on a maker's bench.
Think in the classes the buses generally serve: GPIO for switch, LED, and relay projects; I2C for the wide family of shared-bus hobby sensors; SPI for small displays and memory; UART for board-to-board serial links. Which specific parts fit is a per-project decision, as with any host.
Limits and safety
Oneira's pin counts, voltage levels, and current limits are not yet published. Check the current documentation before designing a circuit that depends on specific electrical assumptions, and treat the buses — not imagined numbers — as the planning surface.
The scope is low-voltage hobby electronics. Household mains power — outlets, fixtures, appliances, anything on the supply side of a wall plug — belongs to a qualified electrician, no matter what device sits on the bench.

Questions, answered
Yes. Oneira ships hardware tools on GPIO along with I2C, SPI, and UART.
Those electrical details are not yet published. Check the current Oneira documentation before designing a circuit that depends on a specific pin count, voltage, or current limit.
GPIO. One pin driving one LED gives one visible result, and I2C sensors, SPI displays, and UART links can wait until a project asks for them.
Treat mains power as electrician territory. Oneira's hardware tools are for low-voltage hobby electronics; anything touching household mains wiring belongs to a qualified electrician.
No Oneira subscription is required for the core product. Parts, sensors, and any third-party services in a project are your own purchases.
