The 1KVA-SINE-WAVE-POWER-INVERTER is built around the ATmega328-PU, from the AVR/Arduino family.

How big is the 1KVA-SINE-WAVE-POWER-INVERTER PCB?

The 1KVA-SINE-WAVE-POWER-INVERTER measures 111.1 × 44.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 1KVA-SINE-WAVE-POWER-INVERTER?

33 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the 1KVA-SINE-WAVE-POWER-INVERTER design files?

From the Ogbonna-Joseph/1KVA-SINE-WAVE-POWER-INVERTER repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the 1KVA-SINE-WAVE-POWER-INVERTER design in my own project?

The repository has no license, so all rights stay with Ogbonna-Joseph. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 1KVA-SINE-WAVE-POWER-INVERTER without the hardware?

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