Redesigned control board for IKEA Uppatvind with smart capabilities

Redesigned control board for IKEA Uppatvind with smart capabilities.

The IKEA's air purifiyer lineup is very affordable, and that's especially true for the cheapest Uppatvind. Although it is not the most powerful, it can still improve air quality in a smaller room, while not taking a lot of space. Regardless of the pricepoint, there is not a lot of commercial options, that are this compact.

Smart uppatvind: common questions

What microcontroller does the Smart uppatvind use?

The Smart uppatvind is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the Smart uppatvind PCB?

The Smart uppatvind measures 74 × 36 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Smart uppatvind?

66 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the Smart uppatvind design files?

From the moucha19/smart-uppatvind repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Smart uppatvind design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which moucha19 chose for the repository.

Can I test firmware for the Smart uppatvind without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
