With battery shown, you can take a walk outside while charting your path
on the computer back in your office.
Now with all these pieces working it is time to review and prepare for the
next layout of this system. Since this was the Alpha build much has been
learned and new requirements have surfaced. Included in the next build will
be the foundation for Mesh Networking of the 900MHz. Much needed attention
to the power supply and rechargeable batteries is first on the list. Lithium
Ion looks like the best power per package but needs proper charging. If you
you have any suggestions please email me with what you would like to see. If
you want to buy Beta boards for your own testing and development please let me
know.
