Portable
it has built-in battery interface charger for mobile applications.
Function
it performs 4 functions at once: WiFi scanner, Bluetooth scanner, Beacon scanner, Beacon broadcaster.
Online
it can collect data and be configured over the internet in realtime.
Time
it customises in LESS time than making a cup of coffee (e.g. 3 minutes).
Ultra Affordable
Mesh26 makes it affordable for compute owners to deploy their OWN infrastructure at home.
No more paying for home devices that are actually controlled by Cloud Compute remotely, with Cup Compute you can experience the advantages of having full control of the device you paid for.
Beside its cost and size, the most important feature of Cup Compute is how easy it is for everyday people to INDEPENDENTLY control 100% what it will or will not do.
Most Cloud Compute devices cannot be changed to function exactly as you like and probably will no longer work if the Cloud Compute is not available.
MS26 hardware is available at ultra low-cost e.g. from Aliexpress.

As shown in above table there is a 20% increase in AU$ price within 6 months but then the price stabilised, we expect in 2026 the fully delivered cost of MS26 to remain around the price of a cup of coffee in many countries (e.g. AU$4.50 in Australia)
Considering MS26's ability to prevent future pandemics, even as a pure public health investment, governments can afford to fund a MS26 for every citizen - which costs substantially LESS than that of a single COVID19 vaccine shot.
MS26's onboard battery charger support larger batteries, but 2000mAh is more than enough power for 24 hours of continuous operation for use in mobile and solar-powered applications.
Cheap 50 x 75 mm resealable plastic bag (to protect Cup Compute with battery plugged in).
Thicker Bag
The resealable plastic bag is very thin but does help keep Cup Compute, the battery and the cable between them together as a single unit.
If you are dropping the whole thing into your backpack you might need a thicker bag.
Antistatic Bag
You cannot use the antistatic bag that comes with Cup Compute as that will block WiFi and Bluetooth signals. But you should keep that anti-static bag around, so you can reuse it to send your Cup Compute to next owner when you upgrade from a Wireless Station to a Home Station.
MS26 - on the LEFT in the above image is the USB Type-C version
MS26m - on the RIGHT in the above image is the Micro USB version
MS26m is still supported but should not be used if MS26 is available.
2. USB Chipset
Most models use a CH340G or compatible USB chip, which prefers a 5.0V supply but can handle up to 6.5V maximum, so direct attach to solar panels with 6V output should be OK in most cases.
Mesh Station 2026 (MS26) is implemented with the Wemos Lolin32 Lite which has been discontinued, but MANY clones are still being manufactured and are available widely at ultra low cost.
Note there are TWO versions of Wemos Lolin, MS26 is the cheaper "Lite" version, NOT the "Standard" version:
