PulseGen: common questions

What microcontroller does the PulseGen use?

The PulseGen is built around the STM32G474RXTX, from the STM32 family.

How big is the PulseGen PCB?

The PulseGen measures 46 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PulseGen?

45 components, from 19 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 PulseGen design files?

From the jelson/rulos 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 PulseGen design in my own project?

Yes, under the terms of its GPL-3.0 license, which jelson chose for the repository.

Can I test firmware for the PulseGen 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.
