Vending · machines · equipment

The screen and the brain inside your machine.

Machine builders need a display that fits their enclosure and a computer that controls the machine. We supply both — an open-frame touch display and an Android board with RS232/RS485, CAN and GPIO — designed together and tested as one unit.

Open-frame Android touch display module for embedding in machines

How it works

One board talks to the machine and drives the screen.

Inside a vending machine or a piece of equipment, the Android board does two jobs: it runs the touch interface on the open-frame display, and it talks to the machine controller over RS232/RS485 (Modbus), CAN or GPIO. We design both halves together and test them as one unit.

Use cases

Where this hardware works.

Common applications by industry, and the setup we would typically build for each. Every project starts from your site, so sizes and parts change with it.

Smart vending

A touch screen that sells

The touch screen shows products, takes cashless payment and plays promotions, while the board reports sales and stock to the operator.

Typical setup: An open-frame display in the door; the Android board talking to the vending controller and payment module over serial.
What matters here: One board for the screen, payment and machine control.

Grab-and-go fridges

Unlock, take, pay

Shoppers unlock the door with a card or an app, take what they want and pay as they close it.

Typical setup: An Android board with GPIO for the door lock and camera input; RK3576 or RK3588 when products are recognised by vision.
What matters here: Dependable lock control and recognition on the device.

EV charging

The screen on the charger

Drivers start a session, pay and follow the charging status on the charger itself.

Typical setup: A higher-brightness open-frame display with projected-capacitive touch that works with capacitive gloves; serial to the charge controller.
What matters here: Readable outdoors and usable with capacitive gloves.

Parcel lockers

One terminal, many doors

Couriers drop parcels, recipients collect them with a code, and the terminal opens the right door.

Typical setup: An Android terminal driving the lock boards over RS485, with touch display and scanner in the locker column.
What matters here: Reliable RS485 control and unattended operation.

Industrial control and energy storage

Operator panels on machines and cabinets

Operators check status and alarms and change settings on a touch panel built into the machine or cabinet.

Typical setup: An open-frame display with Android or Windows 11; RS232/RS485, CAN and GPIO to the controller.
What matters here: Fits the cut-out and keeps running unattended.

Medical, lab and fitness equipment

The interface inside the instrument

Lab instruments, treatment equipment and fitness consoles get a touch interface that belongs to the product.

Typical setup: Display and board designed into the housing, talking to the instrument controller over serial.
What matters here: A screen that fits the design; the device maker certifies the finished equipment.

Why iTEMP

One team, from the board to the software.

A typical rollout stitches together a board vendor, a panel supplier, a firmware contractor and a software team. We design the board, build the display and write the firmware ourselves, then integrate your software — so when something has to change, one team changes it.

04 Software and testingIntegrated and burned in
Your machine app talks to the board over serial, CAN or GPIO — our RS485 and Modbus guide shows how. Android or Windows 11.

Custom development

Built to your spec.

Standard products ship as they are. For a project, any of these can change — and because the board, display and firmware are ours, the change is made at the source.
