Overview

Tank is an open-source printed circuit board by frangipp, from the frangipp/TANK-PCB repository on GitHub. It is a 4-layer board of 70 × 70 mm with 163 parts on 120 nets, routed with 785 tracks and 319 vias.

It is built around the STM32G431KBT6, HC-05 and DCP3601NMR, with the LMD18200T, SQJ459EP-T2_BE3 and BQ24800RUYR among its other parts. Its parts include 56 capacitors, 55 resistors, 17 ICs, 10 connectors and 7 diodes. It belongs with the STM32 boards of this library.

Dans le cadre d’un projet étudiant en binôme à l’ESEO Angers.

Développement d’un "TANK" : un petit robot à entraînement différentiel. Il sera commandé par Bluetooth via une application Android. Pour l’utilisateur, l’objectif sera d’entrer en collision avec le TANK adverse. Chaque collision rapporte des points.

Détails techniques :

  • Microcontrôleur STM32G431
  • Module Bluetooth HC-05
  • Négociation USB Power Delivery (STUSB4531)
  • Chargeur et BMS pour batterie Li-ion (power management : BQ24800, équilibrage des cellules : BQ76905)
  • Driver moteur LMD18200. Moteurs jusqu’à 55 V (théorique) et 3 A. On utilise ici des Maxon en 12 V.

À titre personnel, ce projet me permet surtout de tester la norme USB Power Delivery ainsi que la charge d’une batterie.

Questions

How big is the Tank PCB?

It measures 70 × 70 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Tank use?

163 parts, built around the STM32G431KBT6, HC-05, DCP3601NMR and LMD18200T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Tank KiCad files?

From the frangipp/TANK-PCB repository on GitHub, at the commit this page was made from: the board is tank.kicad_pcb and its schematic bms.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Tank design in my own project?

Its repository states no licence, so its author keeps all rights: ask frangipp before reusing the design.
