1.1.4. Outlook and Dimension#
1.1.5. 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(SCL); Yellow to P20(SDA)). 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: 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 )

2.While using AI cameras, if there is an error tip occurring while clicking downloading, it might be the corrupted extensions of the PlanetX.
Details of the corrupted might be these two reasons:
(1)The version of the extension is not the newest, please try creating a new project and add the extensions again.
(2)The conflict emerged due the adding of both the PlanetX and PlanetX-AI, please click the part circled in red in the picture “JaveScript”to switch the program screen, click the explorer and delete PlanetX or PlanetX-AI according to your demand.
After deleting, it should work now.
After deleting, if you find the loss of the visual block, please try adding the extensions again. If it doesn’t work, please try resetting the MakeCode with the tips in below picture.
