Microbit + HuskyLens 2
Darkw00d 2026-03-12 00:11:06 422 Views4 Replies I have recently brought a huskylens 2 for microbit projects, using a kitronik 16 servo extension board (https://kitronik.co.uk/products/5694-compact-16-servo-driver-board-for-the-bbc-micro-bit?srsltid=AfmBOoq17XJxx0IzpPvsdTQl9nkhX-2M28JlK4kqFEdzrC29Ort4GtMn
) .
I have added the huskylens 2 extension to make code and can get it to initiate via i2c, using the servo plugs for power (gnd and v) and green to edge pin 19 and blue to edge pin 20 and also confirm that face detection for example is loaded.
Ive run the attracted code to show if face detected or to show no of faces detected and it shows as 0 consistency, despite the huskylens 2 leds showing as identifying.
Also wierdly when I try different code it will run the huskylens 2 will reboot when a face is detected, but when I use the same set up, but use object detection in huskylens it will detect an object fine but will restart when I move to face and identify one.
Ive also tried serial protocols and using a micromate (forcing the pins).
Could you please give me a any pointers as to where I'm going wrong?
You can try reloading the Huskylens2 graphical library first! Also, send over screenshots of the sample code that’s giving you trouble. And double-check that your initialization code isn’t inside the loop
niu.yixuan Thank you so much for the speedy response.
Yes updated firmware to 1.2.2
Yes I've been trying to power it with usb c and testing it with that example and no joy.
Darkw00d First, confirm that your HUSKYLENS 2 has been updated to firmware version 1.2.2. We fixed multiple communication instability issues in this version, and updating the firmware is a mandatory prerequisite for resolving the problem.

Second, when using HUSKYLENS 2 with micro:bit and MakeCode, HUSKYLENS 2 must be powered independently via its Type-C port. The expansion board mentioned in the wiki is a recommended option (not mandatory) — if using this recommended expansion board, HUSKYLENS 2 can be powered directly without an additional Type-C power supply.

We also recommend testing with the sample programs provided in the above tutorials to isolate the root cause of your issue.
niu.yixuan Do you have any other ideas of what I might try based on my response above? Thank you for your help!
