About the Programmer PCB

Programmer is an open source PCB design by kevinlutzer, published on GitHub. It is a 2-layer board measuring 19.3 × 55.1 mm, with 8 components from 6 distinct parts.

Other key parts include the Adafruit CP210XN Friend. By type, the board carries 2 transistors, 2 switches, 2 capacitors, 1 IC and 1 connector.

It belongs with the iot & wireless, sensors and usb & debug tools designs in this gallery.

From the project

An IOT device built of the raspberry pi

The Room Environment Monitor (REM) project was something that I started back in 2017. I wanted a small IoT device that could tell me if there was a concerning amount of volatile organic compounds (VOCs) and CO2 in my workshop. I built the first version based on a Raspberry Pi Zero, CCS811 air quality monitor, and a BME280 humidity and temperature sensor.

I went through multiple iterations of the project with the overall objective to reduce cost while increasing the precision of the measurements being made. At that time, the CCS811 sensor cost about 40 dollars alone, which brought the V1 bill…

Programmer: common questions

How big is the Programmer PCB?

The Programmer measures 19.3 × 55.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Programmer?

8 components, from 6 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 Programmer design files?

From the kevinlutzer/room-environment-monitor 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 Programmer design in my own project?

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