MCU stm32L05: common questions
What microcontroller does the MCU stm32L05 use?
The MCU stm32L05 is built around the STM32L052K6Tx, from the STM32 family.
How big is the MCU stm32L05 PCB?
The MCU stm32L05 measures 37 × 32 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the MCU stm32L05?
30 components, from 18 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 MCU stm32L05 design files?
From the m0in92/common_pcb_circuits 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 MCU stm32L05 design in my own project?
The repository has no license, so all rights stay with m0in92. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MCU stm32L05 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.
