First official release of the analog DC Motor Driver developed for the E05 course at Inatel. This hardware is optimized for single-layer fabrication and robust manual assembly.

✨ Key Features

  • Analog Switching: BC547 NPN transistor driving a 5V SPDT Relay (Songle SRD).
  • Protection & Stability: 1N5408 flyback diode for inductive spikes and a 10kΩ pull-down network for the push-button input.
  • Status Indicator: Integrated red LED for output state feedback.
  • DFM Optimized: Single-layer (B.Cu) routing, oval THT pads for easier hand-soldering, and teardrop junctions for enhanced mechanical resistance on phenolic boards.

📦 Assets Included

  • Gerber Files: Ready for professional manufacturing via JLCPCB (GERBER-Transistor_Driver.zip).
  • B.Cu PDF: 1:1 scaled layout print ready for thermal transfer and local lab etching.
  • Source Files: Complete KiCad project workspace (.kicad_pro, .kicad_sch, .kicad_pcb).
