Board b
About the Board b
Board b is an open source PCB design by Takazudo, published on GitHub. It is a 2-layer board measuring 110 × 85 mm, with 75 components from 40 distinct parts.
Other key parts include the C2071044, C347423, C459702 and C666306. By type, the board carries 32 capacitors, 18 resistors, 6 ICs, 5 connectors, 3 LEDs and 3 inductors.
From the project
The renewed design separates the USB-PD input module from synth conversion.
The renewed design separates the USB-PD input module from synth conversion.
The root combined-board KiCad files remain the historical v0.4.0 reference. Use the current architecture for interface roles and the release gates before exporting an order package.
Board B's screw-terminal revision is 110 × 85 mm with two copper layers, 2 oz outer copper and 76 schematic components. Two top-side WJ500V-5.08-2P / C8465 blocks have wire entries facing left. J6 carries GND/−12 V and J7 carries +5 V/+12 V. J8/J9 are retired. The active board has a plain left edge and requires no printed terminal guard.
