Eleph: common questions

What microcontroller does the Eleph use?

The Eleph is built around the STM32F103C8T6, from the STM32 family.

How big is the Eleph PCB?

The Eleph measures 36 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Eleph?

55 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Eleph design files?

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

Can I use the Eleph design in my own project?

Yes, under the terms of its GPL-3.0 license, which FeruzTopalov chose for the repository.

Can I test firmware for the Eleph 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.
