Kryptonite
About the Kryptonite PCB
Kryptonite is an open source STM32 PCB design by samienr, published on GitHub under the MIT license. It is a 2-layer board measuring 26.3 × 17.1 mm, with 27 components from 15 distinct parts.
Its main chip is the STM32F072CBU6, from the STM32 family. Other key parts include the ATECC608B-MAHDA-S, MCP1700T-3302E/TT and USBLC6-2SC6. By type, the board carries 12 capacitors, 6 resistors, 4 ICs, 2 connectors, 1 crystal and 1 switch.

Kryptonite: common questions
What microcontroller does the Kryptonite use?
The Kryptonite is built around the STM32F072CBU6, from the STM32 family.
How big is the Kryptonite PCB?
The Kryptonite measures 26.3 × 17.1 mm, has 2 copper layers and is 0.7912 mm thick.
How many components are on the Kryptonite?
27 components, from 15 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 Kryptonite design files?
From the samienr/kryptonite 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 Kryptonite design in my own project?
Yes, under the terms of its MIT license, which samienr chose for the repository.
Can I test firmware for the Kryptonite 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.
