PixelFonts is a condensed bitmap font family built by mcer12 for low-resolution displays, designed to maximize characters per line without sacrificing legibility.
The library integrates directly with AdafruitGFX and U8g2, the two most common embedded display libraries, requiring no changes to existing rendering calls. Fonts ship in multiple heights and weights, include a 3D shadow variant, and support accented lowercase characters. Every typeface includes a BDF source file, meaning modifications are straightforward in any standard font editor.
The full project on GitHub is worth reading for the glyph design decisions and the tradeoffs made to fit accented characters within tight pixel budgets. For color LCD users, the article also points to a companion technique: subpixel rendering, which triples effective horizontal resolution by addressing RGB phosphor strips individually.
