About the TAILS PCB

TAILS is an open source STM32 PCB design by Mario-dango, published on GitHub. It is a 2-layer board measuring 100 × 100 mm, with 80 components from 49 distinct parts.

Its main chip is the YAAJ_BluePill, from the STM32 family. Other key parts include the LM7805_TO220, LM317_TO-220 and Pololu_Breakout_A4988. By type, the board carries 20 connectors, 18 capacitors, 18 resistors, 12 diodes, 3 ICs and 3 modules.

It belongs with the robotics & motion designs in this gallery.

From the project

T.A.I.L.S. - Ecosistema de control para brazo robótico (3-DOF + Gripper). Incluye Interfaz Gráfica en Python (PyQt5), Firmware C/C++ (STM32 HAL) y diseño de PCB.

Este directorio contiene todo el proyecto de diseño de hardware (Hardware Design) de la placa de control principal para el brazo robótico T.A.I.L.S.

El diseño fue realizado íntegramente en KiCad, buscando crear un placa base robusta que elimine el cableado protoboard, minimice el ruido eléctrico y centralice el control de potencia y señales.

El cerebro de la placa es un microcontrolador STM32F103C8T6 (Bluepill). El circuito está dividido en bloques funcionales para facilitar su análisis y mantenimiento:

TAILS: common questions

What microcontroller does the TAILS use?

The TAILS is built around the YAAJ_BluePill, from the STM32 family.

How big is the TAILS PCB?

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

How many components are on the TAILS?

80 components, from 49 distinct parts. The full bill of materials is listed on this page.

Where can I download the TAILS design files?

From the Mario-dango/TAILS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the TAILS design in my own project?

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

Can I test firmware for the TAILS 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.
