Are there any plans to release a BSP that can be used with Arduino?

[nfs0619]

Hello,
At the moment, we do not have plans to support Arduino. We recommend using the development environments provided in our Wiki. If you encounter any issues during use, please feel free to contact our technical support at techsupport@seeed.io.

Could you provide me a tutorial for building Nordic Matter samples for XIAO nRF54L15 board?

[nfs0619]

Thank you for your feedback. At present, Matter is not yet fully supported on the XIAO nRF54L15. Our team is working on the development and we plan to provide Matter support in the future.

Can I upload to XIAO_nRF54L15 via USB?
Or do I need to use SWDIO/SWCLK?

[bleaaach]

Hi, you can upload the program via USB; no additional interfaces are needed. Just follow our tutorial.

Hi,

Could you provide a Zigbee tutorial for XIAO nRF54L15.
There is Zigbee support with the last nRF Connect SDK v3.1.0 version: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/zigbee.html

Regards

[bleaaach]

Hi, thank you for your feedback. We have already passed it on to the product line and are waiting for their response. We will get back to you as soon as we receive any reply.

Hi, more Zigbee tutorials will be released later. Currently, they are still in the verification phase. You can follow our wiki for the latest updates.

Hi, I didn"t manage to get the low power example working. Is it supposed to be battery powered to get to the couple of uA goals ?
When I power it from 3.3V pin, I get about 750uA consumption (and I didn't forget to add overlay with
&pdm_imu_pwr{
/delete-property/ regulator-boot-on;
};
)
When powering from battery pin, I get about 250uA, and from 5V input, I get about 400uA.

Do you have a precise tutorial to reproduce zephyr low power example ??

Thx !

Hi,

1. The issue lies in the configuration of the app.overlay and prj.conf files. After making modifications, the test results are consistent with those in the wiki.

2. Specific modification requirements:
   2.1 Modify the app.overlay file with the following content:

   &pdm_imu_pwr {
       /delete-property/ regulator-boot-on;
   };
   

   2.2 Modify the prj.conf file with the following content:

   CONFIG_PM_DEVICE=y
   CONFIG_NRFX_POWER=y
   CONFIG_POWEROFF=y
   CONFIG_HWINFO=y
   CONFIG_CRC=y
   CONFIG_GPIO=y
   

3. Important note for power consumption testing:
   The power supply should be connected to the battery interface on the back of the board; do not use the Type-C interface for testing. This is because the Type-C path includes a voltage step-down circuit, which will increase power consumption. Additionally, the recommended power supply voltage ranges from 3.7V to 4.2V.

where can I find XIAO nRF54L15 Kicad symbol and footprint?

[nfs0619]

Hello, you can find the KiCad files we provide at the following link:

Hi,

what is the charging current?

[bleaaach]

Hi, please refer to the schematic diagram. The default/factory circuit sets the charging current to approximately 200 mA (when powered via USB and the battery is not fully charged).
