HnR2026 PCB Debugger: common questions

What microcontroller does the HnR2026 PCB Debugger use?

The HnR2026 PCB Debugger is built around the STM32F103C8Tx, from the STM32 family.

How many components are on the HnR2026 PCB Debugger?

14 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the HnR2026 PCB Debugger design files?

From the evarexis/HnR2026_PCB_Debugger repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the HnR2026 PCB Debugger design in my own project?

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

Can I test firmware for the HnR2026 PCB Debugger 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.
