STM32 JNBG: common questions

What microcontroller does the STM32 JNBG use?

The STM32 JNBG is built around the STM32F030F4Px, from the STM32 family.

How big is the STM32 JNBG PCB?

The STM32 JNBG measures 52.5 × 51.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the STM32 JNBG?

33 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the STM32 JNBG design files?

From the Ahmed0Sherif/STM32_JNBG repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the STM32 JNBG design in my own project?

Yes, under the terms of its MIT license, which Ahmed0Sherif chose for the repository.

Can I test firmware for the STM32 JNBG 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.
