DH11-I2C: common questions

What microcontroller does the DH11-I2C use?

The DH11-I2C is built around the arduino_mini, from the AVR/Arduino family.

How big is the DH11-I2C PCB?

The DH11-I2C measures 27.9 × 3.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DH11-I2C?

7 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the DH11-I2C design files?

From the pmacik/electronics repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the DH11-I2C design in my own project?

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

Can I test firmware for the DH11-I2C 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.
