Hi All,

I would like to thank you all for your efforts in making this campaign successful. These have been tough times due to the pandemic, but we were able to pull through with great effort put in from all sides.

All orders have been delivered to Crowd Supply and they will be disbursed to backers as soon as possible. Please feel free to send me updates on the shipments. Each unit has been tested individually for manufacturing defects and performance. In case of any failures on the customer end, please inform us so that we can fine tune our production test methods.

Note that we have already added all the required documents, source files and hardware design documents on GitHub

Looking forward to hearing from backers about their experience with the product.

Once again I thank you for your support.
