About the Stm32-lcd thermometer PCB

Stm32-lcd thermometer is an open source STM32 PCB design by seesee010, published on GitHub. It is a 2-layer board measuring 46.2 × 23.5 mm, with 31 components from 15 distinct parts.

Its main chip is the STM32F103C8TX, from the STM32 family. Other key parts include the AMS1117-3.3 and SHT31-DIS. By type, the board carries 13 capacitors, 9 resistors, 4 connectors, 3 ICs, 1 crystal and 1 switch.

It belongs with the displays & leds and sensors designs in this gallery.

From the project

A PCB Project, from pcb to C - all without any libs. Functionality: A pcb - with CPU, Sensor, Display. The core functionality is to gain data (from the sensor) and to show them on screen (per spi). Sensor is speaking per i2c

This is my project, fully made with KiCad. The purpose is that it will show temp and hum on display (spi).

Stm32-lcd thermometer: common questions

What microcontroller does the Stm32-lcd thermometer use?

The Stm32-lcd thermometer is built around the STM32F103C8TX, from the STM32 family.

How big is the Stm32-lcd thermometer PCB?

The Stm32-lcd thermometer measures 46.2 × 23.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32-lcd thermometer?

31 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 Stm32-lcd thermometer design files?

From the seesee010/stm32-lcd-thermometer 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-lcd thermometer design in my own project?

The repository has no license, so all rights stay with seesee010. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Stm32-lcd thermometer 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.
