About the Tiramisu PCB

Tiramisu is an open source PCB design by esicoe, published on GitHub. It is a 4-layer board measuring 154.1 × 147 mm, with 312 components from 23 distinct parts.

Other key parts include the SRV05-4, CD74HC4067M, AMS1117-3.3, RP2354B and TLV73311PDBV. By type, the board carries 158 capacitors, 132 ICs, 15 resistors, 2 connectors, 2 switches and 1 crystal.

It belongs with the sensors and dev boards & breakouts designs in this gallery.

From the project

Tiramisu is a drawing tablet for osu! that tracks a magnet-tipped pen with a grid of 120 Hall-effect sensors and reports its position over USB 1000 times a second. That's the USB Full-Speed ceiling, and 7.5x the 133 Hz of a Wacom CTL-472.

It's my independent prototype of the Hall-effect tablet we're building at Wonkle. The board and firmware go by aim1k in the source.
