Its main chip is the STM32F407VET6, from the STM32 family. Other key parts include the AMS1117-3.3, SRV05-4HTG-D, TMC2209-LA-T, TPS62933FDRLR and 74HC4051D,653. By type, the board carries 95 capacitors, 39 resistors, 16 connectors, 14 ICs, 9 switches and 6 diodes.
It belongs with the robotics & motion designs in this gallery.
From the project
uma impressora 3d simples, com o objetivo de ser modular, durável e open-source.
Projeto "Harpia Ninho" é uma impressora 3D projetada para ser open-source (leia a licença atual do projeto antes de usar), durável, modificável e atualmente ficando mais fácil de consertar e fazer módulos de expansão, tipo um LAN/Ethernet, mais NTC, driver de passo, FRAM e muito mais. Ele foi feito para ATX-20 ou ATX-24; licença "CERN-OHL-S-2.0". ## contexto Eu queria uma impressora 3D barata, eficiente, personalizada e open-source que pudesse ser muito modificada.

Harpia: common questions
What microcontroller does the Harpia use?
The Harpia is built around the STM32F407VET6, from the STM32 family.
How big is the Harpia PCB?
The Harpia measures 93.6 × 93.8 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Harpia?
182 components, from 45 distinct parts. The full bill of materials is listed on this page.
Where can I download the Harpia design files?
From the todio1155/harpia repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Harpia design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which todio1155 chose for the repository.
Can I test firmware for the Harpia 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.
