About the Tinyfc core PCB

Tinyfc core is an open source STM32 PCB design by wangyeee, published on GitHub under the BSD-3-Clause license. It is a 4-layer board measuring 36 × 44 mm, with 103 components from 51 distinct parts.

Its main chip is the STM32F405RGTx, from the STM32 family. Other key parts include the MPU9250, MP2162, AT24C512C-SSHD, DPS310 and 74AHC1G86. By type, the board carries 29 resistors, 24 capacitors, 17 connectors, 10 diodes, 8 ICs and 3 inductors.

It belongs with the robotics & motion, rf & radio and sensors designs in this gallery.

From the project

Collections of hardware design related to my drone project.

This board is designed to be used with Paparazzi UAV software stack. Complete software support is still under development, mainly the barometer driver and data persistence support for EEPROM.

Tinyfc core: common questions

What microcontroller does the Tinyfc core use?

The Tinyfc core is built around the STM32F405RGTx, from the STM32 family.

How big is the Tinyfc core PCB?

The Tinyfc core measures 36 × 44 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Tinyfc core?

103 components, from 51 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tinyfc core design files?

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

Can I use the Tinyfc core design in my own project?

Yes, under the terms of its BSD-3-Clause license, which wangyeee chose for the repository.

Can I test firmware for the Tinyfc core 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.
