Tensigral lamp: common questions

What microcontroller does the Tensigral lamp use?

The Tensigral lamp is built around the STM32F042F4PX, from the STM32 family.

How big is the Tensigral lamp PCB?

The Tensigral lamp measures 99 × 99.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tensigral lamp?

83 components, from 31 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Tensigral lamp design files?

From the cnlohr/tensigral_lamp repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Tensigral lamp design in my own project?

Yes, under the terms of its MIT license, which cnlohr chose for the repository.

Can I test firmware for the Tensigral lamp 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.
