README
README.mdAn easy to use discrete 4 bit DAC
Andromeda is an easy to use, discrete, four bit DAC. It has been designed for higher voltages in mind, utilizing a 741 op amp you can attain ~+/-23 volts. It also contains an on board potentiometer for input offset voltage adjustments.
What you will need
- External plus and minus power supply
- Four switches or a MCU for input @ 5V
Uses
- Digitally adjustable breadboard power supply
- Fine tuned millivolt or microvolt supply
- The board itself can also be used as a summing amplifier if input resistors are adjusted.

Questions
How big is the 4bitDAC PCB?
It measures 54.1 × 29.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 4bitDAC use?
13 parts. 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 4bitDAC KiCad files?
From the camerontbelt/Andromeda repository on GitHub, at the commit this page was made from: the board is KiCad/4bitDAC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 4bitDAC design in my own project?
Its repository states no licence, so its author keeps all rights: ask camerontbelt before reusing the design.
