About the PracticeBoard PCB
PracticeBoard is an open source PCB design by philipturner, published on GitHub under the MIT license. It is a 2-layer board measuring 34.7 × 59.3 mm, with 69 components from 4 distinct parts.
Other key parts include the XMC1100. By type, the board carries 60 resistors, 6 connectors and 3 ICs.
It belongs with the audio designs in this gallery.
From the project
Objective: Gather as much data as possible about the TIA sensor of an STM, using both theory and experiment.

Deadline: September 30, 2025 for the first physical prototype
Three simulation tasks, in chronological order 1) Understand/simulate why coarse tip approach takes so long - Understand specific algorithms for moving the coarse motor (approach & retract) without frictional backlash causing a tip crash - Understand maximum speeds of piezo motors 2) Simulate imperfect DAC-driven cancellation with a fixed value compensation capacitor - Use the tip-sample capacitance of a plausible…
