Echo Ayla80: common questions

What microcontroller does the Echo Ayla80 use?

The Echo Ayla80 is built around the STM32F411RET6, from the STM32 family.

How big is the Echo Ayla80 PCB?

The Echo Ayla80 measures 380 × 128 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Echo Ayla80?

339 components, from 33 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Echo Ayla80 design files?

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

Can I use the Echo Ayla80 design in my own project?

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

Can I test firmware for the Echo Ayla80 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.
