Prototype
TrucLink Pro
The Core controller plus a 4.3 inch touch screen
Gets the job done at the machine when there is no phone to hand, and when the network is down.
Pro keeps the whole machine-control side of Core (same pin map, same loop, same flash buffer) and adds a 4.3 inch touch screen with a rotary knob.
That boundary is a precondition of the design: the part that switches 220 V and the part that records revenue are not to be touched just because someone wants a screen. Core’s control firmware runs on Pro unchanged.
Highlights
- Usable with the network downThe on-machine screen answers the common questions without a server
- The safety-critical part is untouchedThe knob and the fan are additions; the control loop and the revenue path are unchanged
- One knob instead of three buttonsFaster when one hand is already busy
- Four-corner wall mountFlat tabs, M4 holes with countersinks
How money is handled
Pro does not take cash either, but the screen shows staff the day's numbers at the machine without opening a phone.
- Numbers on the screen Today's count and the running total sit on the main page
- Price list per machine Each machine prices each item and size; change it in the app and the machine picks it up
- Shift close on the spot Staff open and close the shift, enter the counted cash, and it reconciles against the machine
- Sales started at the machine still bill Started on the screen or commanded from the app, both are recorded the same way
