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
