  • Flashing: sudo ./openocd_flash.sh

Flashing via AC6 with STM32 Blue Pill

The AC6 stuff is deprecated but the blue pill is still needed.

PCB fabrication constraints:

  • Dims: 70mm x 70mm
  • Layers: 4
  • Thickness: 1.6mm (can vary, thicker = sturdier)
  • Surface finish: HASL Lead free or ENIG (more expensive)
  • Material: FR4

Assembly constraints:

  • SMT Pads: 169
  • Thruhole: 23 (pin headers only)
  • Assembly sides: both

This project is being launched with the help of HEG Alpha to make science more accessible. Custom 2 channel and 19 channel headsets are available by Bernard Markus.
