From the project

The Serial Snooper is a UART data logger with automatic baud rate detection, real-time data stamping and a command-line-interface for configuration, running on an STM32F3 microcontroller.

The Serial Snooper is a UART data logger with automatic baud rate detection, real-time data stamping and a command-line-interface for configuration, running on an STM32F3 microcontroller.

It is utilised in an R&D setting to easily capture logs from devices to speed up catching software and hardware bugs.

1. Plug in USB (5V - resettable fuse limits current to 500mA incase of short circuits damaging the power source). 2. Device powers up, indicated by the green LED. 3. A short moment later, the red LED lights up, indicating that the SD card was successfully initialised. 4. Plug in DB9 cable…

Data-Logger-STM32 design files

The KiCad project lives in the can-caglar/Data-Logger-STM32 repository on GitHub; these links point at the commit this page was built from.

Data-Logger-STM32: common questions

What microcontroller does the Data-Logger-STM32 use?

The Data-Logger-STM32 is built around the STM32F303K8T6, from the STM32 family.

How big is the Data-Logger-STM32 PCB?

The Data-Logger-STM32 measures 104 × 43.3 mm, has 2 copper layers and is 2.63 mm thick.

How many components are on the Data-Logger-STM32?

76 components, from 37 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 Data-Logger-STM32 design files?

From the can-caglar/Data-Logger-STM32 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 Data-Logger-STM32 design in my own project?

The repository has no license, so all rights stay with can-caglar. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Data-Logger-STM32 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.
