Use an IoT box with a PoS


Before starting, make sure the following equipment is available:

  • An IoT box, with its power adapter.

  • A computer or tablet with an up-to-date web browser.

  • Odoo Online or an Odoo instance with the Point of Sale and IoT applications installed.

  • A local network set up with DHCP (this is the default setting).

  • An RJ45 Ethernet Cable (optional, but preferred over WiFi, which is already built in).

  • Any of the supported hardware (receipt printer, barcode scanner, cash drawer, payment terminal, scale, customer display, etc.). The list of supported hardware can be found on the POS Hardware page.



A suggested configuration for a point of sale system.

To connect hardware to the PoS, the first step is to connect an IoT box to the database. To do this, follow these instructions: Connect an Internet of Things (IoT) box to the Odoo database.

Then, connect the peripheral devices to the IoT box.

Device Name



Connect a supported receipt printer to a USB port or to the network, and power it on. Refer to Orders printing.

Cash drawer

The cash drawer should be connected to the printer with an RJ25 cable.

Barcode scanner

In order for the barcode scanner to be compatible it must end barcodes with an ENTER character (keycode 28). This is most likely the default configuration of the barcode scanner.


Connect the scale and power it on. Refer to Connect a scale.

Customer display

Connect a screen to the IoT box to display the PoS order. Refer to Connect a screen.

Payment terminal

The connection process depends on the terminal. Refer to the payment terminals documentation.

Once this is completed, connect the IoT box to the PoS application. To do this, go to Point of Sale ‣ Configuration ‣ PoS, tick the IoT Box option, and select the devices to be used in this PoS. Save the the changes.

Configuring the connected devices in the POS application.

Once set up is done, a new PoS session can be launched.
