## Which one do I need?

* **Debugging or flashing an Arm microcontroller:** [Binho Atira](/hardware/atira/).
* **High-speed I2C, SPI, UART or GPIO from a computer:** [Binho Pulsar](/hardware/pulsar/).
* **I3C, or several buses and ports at once:** [Binho Supernova](/hardware/supernova/).

The [Hardware Comparison Table](/hardware/comparison/) sets them side by side, and [Protocols and Interfaces](/hardware/protocol-support/) lists which protocols each one supports, with speeds and voltages.

## Just unboxed a device?

1. [**Connect a Device**](/hardware/connect-a-device/): USB drivers, the one-time macOS and Linux steps, and checking the device is detected.
2. [**Safety Notice**](/hardware/safety-notice/): review before connecting to a circuit.
3. [**System Requirements**](/hardware/system-requirements/): confirm the computer can run it.

Then open the setup guide for the device above.

## Accessories and third-party products

* [**Accessories**](/hardware/accessories/): the [I3C Target Board](/hardware/accessories/i3c-target-board/), the [PIC18-Q20 CNano Breakout](/hardware/accessories/pic18f16q20-curiosity-nano/), the [mikroBUS Adapter Board](/hardware/accessories/mikrobus-adapter-board/) and the [I2C Mini-DIN Adapter Cable](/hardware/accessories/i2c-mini-din-adapter-cable/).
* [**Third-Party**](/hardware/third-party/): products from other makers that Binho sells, the [Handsfree Probes](/hardware/third-party/handsfree-probes/) and the [USB GPIB Adapters](/hardware/third-party/usb-gpib-adapters/).

## Reference

* [**Hardware Comparison Table**](/hardware/comparison/): specs side by side.
* [**Protocols and Interfaces**](/hardware/protocol-support/): protocol support by device.
* [**Firmware updates**](/guides/firmware-updates/): how to update a device, and what each version changes.
* **Datasheets:** in the document library at [my.binho.io](https://my.binho.io), after signing in.

## Legacy products

[**Binho Nova**](/hardware/nova/), the first-generation adapter, is still supported. See [Legacy Products](/hardware/legacy/).

## Software

[Mission Control 3 and the SDKs](/software/) drive every device above. For topics that span devices, such as I3C and USB operating modes, see the [Guides](/guides/).
