Dual h bridge: common questions

What microcontroller does the Dual h bridge use?

The Dual h bridge is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the Dual h bridge PCB?

The Dual h bridge measures 98.8 × 55.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dual h bridge?

98 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dual h bridge design files?

From the jayanta525/dual-h-bridge repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Dual h bridge design in my own project?

Yes, under the terms of its MIT license, which jayanta525 chose for the repository.

Can I test firmware for the Dual h bridge 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.
