About the Tensilguard PCB

Tensilguard is an open source STM32 PCB design by jayis1, published on GitHub. It is a 4-layer board measuring 100 × 60 mm, with 12 components from 12 distinct parts.

Its main chip is the STM32G431RBTx, from the STM32 family. Other key parts include the SX1262IMLTRT, DRV8872DDA, ICM-42688-P, TMP117 and AD8542. By type, the board carries 7 ICs, 2 capacitors, 1 inductor and 1 resistor.

It belongs with the rf & radio, sensors and test & measurement designs in this gallery.

TensilGuard is a clamp-on, solar-powered, wireless structural-health node that wraps around a structural steel cable — a cable-stayed bridge stay, a suspension bridge hanger, a guyed-mast guy rope, a ski-lift haul cable, a rock-bolt / pre- stressed tendon, or a roadside cable barrier — and continuously measures its tension and internal integrity without removing a single wire from service. It fuses three independent physics modalities…

Tensilguard: common questions

What microcontroller does the Tensilguard use?

The Tensilguard is built around the STM32G431RBTx, from the STM32 family.

How big is the Tensilguard PCB?

The Tensilguard measures 100 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Tensilguard?

12 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tensilguard design files?

From the jayis1/hardware-design-lab repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Tensilguard design in my own project?

The repository has no license, so all rights stay with jayis1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Tensilguard 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.
