TimTime: common questions

What microcontroller does the TimTime use?

The TimTime is built around the STM32L433CCTx, from the STM32 family.

How big is the TimTime PCB?

The TimTime measures 58.2 × 32.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the TimTime?

58 components, from 26 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 TimTime design files?

From the montoyatim01/TimTime repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the TimTime design in my own project?

The repository has no license, so all rights stay with montoyatim01. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TimTime 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.
