Side board
About the Side board
Side board is an open source STM32 PCB design by AndreiVladescu, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 87.5 × 50.6 mm, with 227 components from 47 distinct parts.
Its main chip is the STM32C092KCT6, from the STM32 family. Other key parts include the TPS62933DRLR, NUP2105LT1G, TCAN332DR, TPS56A37RPAR and INA181A1IDBVR. By type, the board carries 103 resistors, 69 capacitors, 16 connectors, 14 ICs, 11 diodes and 4 inductors.
It belongs with the robotics & motion, rf & radio and power & battery designs in this gallery.
From the project
One KiCad project per board: side-board/, power-board/, carrier-cm5/. The lib tables in each point to the shared library in lib/, so custom symbols and footprints go there.

- Connector pinouts come from docs/interfaces.md. Use the same footprint and pin order on both ends of a cable. - Side board: draw the leg cell as one hierarchical sheet, use it three times, and copy the layout with KiCad's multichannel tools. - Tag each fabbed revision (side-board-revA) and put the revision and git hash on the silkscreen. Gerbers, BOM and pick-and-place go in /production//. - Hand assembly: 0402 minimum…

Side board: common questions
What microcontroller does the Side board use?
The Side board is built around the STM32C092KCT6, from the STM32 family.
How big is the Side board?
The Side board measures 87.5 × 50.6 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Side board?
227 components, from 47 distinct parts. The full bill of materials is listed on this page.
Where can I download the Side board design files?
From the AndreiVladescu/Vector-UGV repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Side board design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which AndreiVladescu chose for the repository.
Can I test firmware for the Side board 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.
