The Get Started Guide is available to help you get up and running.

Powering on your BYTE 90

Your BYTE 90 ships powered off to ensure safety and preserve battery health during transportation.

To power on your device for the first time:

  • Press and hold the bottom power button for 1 second to turn your BYTE 90 on.
  • Press and hold the bottom power button for 3 seconds to power your BYTE 90 off.

Important: Charge Before First Use
BYTE 90 arrives with minimal battery charge and requires 1–2 hours of charging before first use.

Once charged, you’re ready to enjoy your new companion!

Accessing the On-Device Configuration Portal

To access the Configuration Portal, connect to the BYTE90-Config Wi-Fi access point from your phone or computer.

The Configuration Portal allows you to scan for available Wi-Fi networks, connect to your selected network, and save your Wi-Fi credentials directly to the device. You can also customize themes, adjust device volume, and configure other system settings. Once connected, your BYTE 90 will remember your Wi-Fi network for future use.

Note: A Wi-Fi connection is required for AI features and automatic time synchronization.

Themes and Effects

Themes and effects are now managed through the on-device Configuration Portal. To access it, connect to the BYTE90-Config Wi-Fi access point from your phone or computer. In the Customize section, you can select your preferred theme or enable visual effects.

Alternatively, you can ask the AI Agent to turn effects on or off by name. For example, say, “Hey, can you turn on Green Tint,” or “Turn on the Glitch effect.”

Sleep mode

To conserve battery life, BYTE 90 automatically enters light sleep after an extended period of inactivity. While in light sleep mode, the device is non-functional. To wake BYTE 90, simply press the button.

Firmware Updates

To update your BYTE 90, visit the Web Configuration Portal. Your device must be connected to your computer using a USB-C cable to complete the update process.

The Web Configuration Portal also allows you to connect to Wi-Fi and configure additional settings, similar to those available in the On-Device Configuration Portal.

Firmware 3.0 Release

Firmware 3.0 is our biggest update to date, introducing a custom AI firmware experience for Byte 90 powered by OpenAI, with optional Xiaozhi AI integration. (An OpenAI api key is required, or activation via Xiaozhi.me)

This update requires either a Byte 90 Series 2 AI Kit, or a new Byte 90 AI Edition device.

Trouble shooting & Questions

What type of battery does Byte 90 use?

Byte 90 is powered by a 1200mAh 3.7V lithium battery (size 103040) with a PH 2.0 connector. The included mount accommodates only these dimensions. For alternative battery sizes, custom 3D-printed mounts are required, noting the housing's 45mm space limitation.

Please ensure you follow these checks before you plug in a battery to avoid any damages to Byte 90

Critical Safety Checks:

  • Verify the battery is 3.7V not 3.9V
  • Check polarity alignment - some batteries have reversed positive/negative positions on the connector
  • Test that your battery functional and charged
  • Handle the battery connect with extra care don't tug on it roughly
  • Inspect the battery connector for damage - ensure it's still properly soldered

Can I use Byte 90 without AI?

BYTE 90 works right out of the box as an interactive designer toy — no AI setup required. Simply skip the AI activation screen to use it as is, or install Firmware 2.0 for the dedicated non-AI experience.

How long is the battery life?

Byte 90 can run for up to 2 days on a full charge. It automatically manages battery life by entering deep sleep when not in use.

How do I charge Byte 90?

Byte 90 charges via the provided USB-C cable and requires 1-2 hours for a full charge. A red flashing light indicates charging is in progress, while a solid red light indicates charging is complete.

What's the password for BYTE 90 Access point?

When Byte 90 enters setup mode, you can establish a local connection between your device and the unit. You'll be prompted to enter a password - the default password is 12345678

My Byte 90 is not turning on

When you first receive your Byte 90, ensure it's fully charged. If the device doesn't turn on after connecting the battery, try powering it via the USB-C connection. If it still doesn't activate, please contact us for support.

Can I use Byte 90 without the battery?

Yes, you can power Byte 90 directly using the included USB-C cable without a battery. Please note that international orders do not include batteries due to shipping restrictions.

My Byte 90 froze, what can I do?

If your Byte 90 freezes and becomes unresponsive, you may need to perform a manual reset. Locate the two tiny buttons on the Byte 90 board labeled "Boot" and "Reset." Press the Reset button to restart the device. If this doesn't resolve the issue, contact us for support as you may need to reflash the firmware.

My Byte 90 randomly restarts itself, what can I do?

If you're experiencing random restarts, this indicates your Byte 90 has very low battery and cannot maintain power. To resolve this, connect the USB-C cable and charge for 1-2 hours.

Can I add custom animations?

Yes, but you'll need programming knowledge to implement new animations. While Byte 90 is developer-friendly, it requires coding skills rather than a no-code approach. The device maintains proprietary animations to ensure brand consistency.

Can I develop custom firmware?

Yes, with programming knowledge you can develop custom firmware for Byte 90. The device runs on an ESP32 S3 microcontroller with Arduino framework. You're free to modify the open source firmware if you have the technical expertise. Contact us if you need to restore the original firmware.

Can you release the 3D files and animations?

The 3D files and animations are not open source. They remain proprietary for brand consistency and maintain brand authenticity. As a product designer, it's essential to protect original designs and creations to support ongoing development and future iterations of the product.
