BME280 module board
- BME280 module measures pressure, temperature humidity, two mode interface one is I2C and other is SPI so in this design BME280 is interfaced by I2C mode.
- 3.3V DC power supply for operating the board
DAC module board
- Digital to analog converter using MCP4721 ic
- pull up resistors for i2c communication protocol SDA and SCL lines
- decoupling capacitor at ouput voltage
- decoupling capacitors at input voltage used MLCC and tantalum as it has low ESR
- 1X5 pin through hole connector to connect the module with controller
LDO voltage regulator
- AMS1117-3.3V ldo regulator convert 5V DC to 3.3V DC
- Two 1x02 connector for vin and vout
- led indication for voltage input with pretected by 1Kohm resistor
- decoupling capacitor at voltage input and voltage output
DHT11 module
- This module measures the temperature and humidity value
- DHT11 sensor (input voltage range 3.3V DC to 5.5V DC)
- 3 pin header conenctor for vcc, gnd and data line
- power on led indication with resistor protection

Questions
How big is the BME280 module PCB?
It measures 17.9 × 9.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BME280 module use?
8 parts, built around the BME280. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the BME280 module KiCad files?
From the pushtiujeniya/Kicad-Projects repository on GitHub, at the commit this page was made from: the board is BME280_ModuleBoard/BME280 module.kicad_pcb and its schematic BME280_ModuleBoard/BME280 module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BME280 module design in my own project?
Its repository states no licence, so its author keeps all rights: ask pushtiujeniya before reusing the design.
