Goals

  1. Fab-able
    • CNC milling double-sided PCB
    • 3D printable frame wheels

Electronics production

The custom PCB was fabricated using a CNC milling machine at FabLab Kannai. Since the board is double-sided, a flipping process was required while aligning the top and bottom layers. That was achieved using “Gerber2Png” developed by FabLab Kerala.
