I received a normal, BW16 in a kit, assembled it and have used it as a WiFi scanner works well. I purchased a few MINI BW16 from Aliexpress, they are smaller form factor however they have a lot of problems with WiFi. I can upload a WiFi scanner program to the normal unit shows networks as expected, however the same program uploaded to MINI BW16 does not show any networks. I have attached a picture of the mini unit. ![IMG_1820](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/5/59622d33eea6dd0b6d8f79b5131dc0637a144dd5.jpeg) ---

Hi @Scientifik, All Realtek official boards are available in this [link](https://www.amebaiot.com/en/ameba-arduino-summary/). Thank you. ---

Lets run some wifi demo to see if it is a HW issue？ [BW16 Arduino — Ameba Arduino AIoT Documentation v1.1 documentation](https://ameba-doc-arduino-sdk.readthedocs-hosted.com/en/latest/bw16-typeb/index.html) ---

I’m not sure what demo you would like me to run, I am running the wifi example already ---

Hi @Scientifik, test with others WiFi [example](https://github.com/Ameba-AIoT/ameba-arduino-d/tree/dev/Arduino_package/hardware/libraries/WiFi/examples) to check between normal BW16 and mini BW16 if most of it are not work with the mini BW16. Probably there is some HW issues on the mini BW16. ---

I said that in my first post. ---

This [https://ameba-doc-arduino-sdk.readthedocs-hosted.com/en/latest/bw16-typeb/index.html](https://ameba-doc-arduino-sdk.readthedocs-hosted.com/en/latest/bw16-typeb/index.html) is still under development. You can refer @KaiFai_Y 's Github to find all WiFi demos. If the normal BW16 works fine, I suggest it is your HW connection and circuit design issue for the mini board. You can refer to [Ameba ARDUINO – Realtek IoT/Wi-Fi MCU Solutions](https://www.amebaiot.com/en/ameba-arduino-summary/) for some HW documents for BW16 [https://docs.ai-thinker.com/\_media/bw16-kit\_specification-v1.2.2-en.pdf](https://docs.ai-thinker.com/_media/bw16-kit_specification-v1.2.2-en.pdf)
