About the Sensor PCB
Sensor is an open source PCB design by Maniek19-ENG, published on GitHub under the MIT license. It is a 2-layer board measuring 21 × 16 mm, with 8 components from 5 distinct parts.
Other key parts include the BME280. By type, the board carries 4 resistors, 2 capacitors, 1 IC and 1 connector.
It belongs with the sensors and dev boards & breakouts designs in this gallery.
From the project
BME280 sensor breakout board designed in KiCad — schematic, 2-layer PCB, BOM and design write-up
A compact (21 × 16 mm) 2-layer breakout board for the Bosch BME280 temperature / humidity / pressure sensor, designed from schematic to manufacturable layout in KiCad. The repository contains the full design source, bill of materials and fabrication instructions, plus a write-up of every design decision for reproducibility.
- Interface: I2C (CSB pulled high selects I2C mode; SDO pulled low sets address 0x76). SDO is broken out on the header so the address can be changed to 0x77 externally. - Pull-ups: 4.7 kΩ on SDA/SCL — suitable for 100–400 kHz on short buses. - Decoupling: separate 100 nF…

Sensor: common questions
How big is the Sensor PCB?
The Sensor measures 21 × 16 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Sensor?
8 components, from 5 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 Sensor design files?
From the Maniek19-ENG/sensor-pcb 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 Sensor design in my own project?
Yes, under the terms of its MIT license, which Maniek19-ENG chose for the repository.
