About the Projected PCB

Projected is an open source STM32 PCB design by jonnor, published on GitHub. It is a 2-layer board measuring 28 × 28 mm, with 43 components from 26 distinct parts.

Its main chip is the STM32L432KBU6, from the STM32 family. Other key parts include the MCP73812T-420I-OT, PCA9306DCUR, MCP1640BT-I/CHY‎, TPS7A0533PDBVT and LIS2DE12TR‎. By type, the board carries 16 resistors, 11 capacitors, 7 ICs, 5 connectors, 1 transistor and 1 battery holder.

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

From the project

Small projects not worthy of dedicated repositories

Etsy.com. Lots of amazing looking products. Mostly rings,pendants. Pure resin or resin+wood. 200-400 NOK. Sometimes glow-in-the-dark. Resin 'stone' with wood base, silver ring inlay. 700-800 NOK.

Maybe silver + resin cast rings has good opportunity? Not found, might be able to push price up.

Oxididation. Electroetching with laser-engraved masks?

Power board for wearable or other battery powered electronics.

Projected: common questions

What microcontroller does the Projected use?

The Projected is built around the STM32L432KBU6, from the STM32 family.

How big is the Projected PCB?

The Projected measures 28 × 28 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Projected?

43 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Projected design files?

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

Can I use the Projected design in my own project?

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

Can I test firmware for the Projected 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.
