OpenDrop V3

We are currently working on the OpenDrop V3, a complete re-design of the OpenDrop digital microfluidics platform with a lot of new features.

New features:

  • Reservoirs – the new electrode array features 4 CT-type reservoirs to experiment with
  • Gold coated 14×8 electrodes array, 2.75mm2 in size, 4mil gaps
  • AC and DC – very exciting , the OpenDrop V3 now has true AC voltage driving capability (up to 300VAC).
  • 32bit AVR SAMD21G18 microprocessor with plenty of memory and power
  • Electronic settings for voltage level, frequency and AC/DC selection
  • Electronic reading of actual voltage level
  • One connector for communication and powering (USB-C)
  • Optical isolation of the high-voltage electronics trough opto-couplers and PhotoMOS
  • New polyphonic audio amplifier and speaker (it’s a synth!)
  • Cartridge presence detection
  • Super flat OLED Display
  • Nice joystick and 2 buttons, 3 LEDs
  • Reset button
  • All files open source, designed on KiCAD
