About the Stm32-ir linescan digit recognizer PCB

Stm32-ir linescan digit recognizer is an open source STM32 PCB design by yzxoi, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 60 mm, with 55 components from 17 distinct parts.

Its main chip is the STM32G0B1RBT6, from the STM32 family. Other key parts include the ITR20001/T, CH340N, XL-SA3191SRWC and AMS1117-3.3. By type, the board carries 29 resistors, 12 ICs, 10 capacitors, 2 connectors, 1 transistor and 1 switch.

From the project

An STM32G0B1-based 8-channel infrared line-scan digit recognizer with custom KiCad hardware, USB-UART acquisition, Q15 preprocessing, and TinyML inference.

Open number.kicadpro with KiCad 10 or newer. The project contains the editable schematic and two-layer PCB, plus project-local symbols and footprints. fp-lib-table and sym-lib-table use ${KIPRJMOD}` paths, so the design does not depend on the original workstation directory.

Stm32-ir linescan digit recognizer: common questions

What microcontroller does the Stm32-ir linescan digit recognizer use?

The Stm32-ir linescan digit recognizer is built around the STM32G0B1RBT6, from the STM32 family.

How big is the Stm32-ir linescan digit recognizer PCB?

The Stm32-ir linescan digit recognizer measures 100 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32-ir linescan digit recognizer?

55 components, from 17 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 Stm32-ir linescan digit recognizer design files?

From the yzxoi/stm32-ir-linescan-digit-recognizer 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 Stm32-ir linescan digit recognizer design in my own project?

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

Can I test firmware for the Stm32-ir linescan digit recognizer 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.
