Hido: common questions

What microcontroller does the Hido use?

The Hido is built around the STM32F102RBTx, from the STM32 family.

How big is the Hido PCB?

The Hido measures 113 × 71.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hido?

146 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hido design files?

From the dottorconti/hido repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Hido design in my own project?

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

Can I test firmware for the Hido without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
