Connection Type: RJ11 to Dupont connector¶

While the micro:bit breakout board doesn’t have the RJ11 connections, we can choose to use a Dupont wire that has the RJ11 connections. We need to connect the RJ11 to the Lens and the other ends connect to the breakout board(Black wire to GND; Red to VCC; Green to P19(SDA); Yellow to P20(SCL)). If the Lens doesn’t work from the start, please try powering it with a standalone power sourse.

Take IoT:bit for an example:

Note:

If you do not use Nezha expansion board to drive the AI Lens, please search with the package through this link: https://github.com/elecfreaks/pxt-PlanetX-AI
Under the one button to acquire mode, you will have to re-learn the objects if you restart the device.
After downloading the code, if the AI lens gets stuck in the starting page with an init AI Lens error instruction, please try to power off the device and restart it. (Or make sure you connect the ready-programmed micro:bit board after the AI Lens connects the breakout board well )

AI Lens firmware update¶

For a better experience of the AI Lens, we are making an irregularly update for the new functions and optimization of the performance, a manually update of the firmware is required after the new version is released.

How to check the current version¶
