Now with droplet feedback reading.<\/p>\n<p>The OpenDrop V4 is modular electrowetting controller. The driver board is equipped with a connector that can host a circuit board cartridge with a 14\u00d78 electrode array and 4 reservoirs. The liquids stay on a thin, hydrophobic foil laminated to the circuit board . The device is powered from USB though an included USB-C cable. All the voltage level are generated on the device and can be set with the built in soft menu from 50-260 Volts, DC or AC.<\/p>\n<p><strong>OpenDrop Cartridges<\/strong><br \/>\nThe modular concepts of the OpenDrop V4 allows different configurations of cartridges:<br \/>\n1. The device comes with a preinstalled gold coated electrode array board that can be coated with any dielectric layer and hydrophobic coating suitable for electrowetting.<br \/>\n2. The <a href=\"https:\/\/gaudishop.ch\/index.php\/product\/open-cartridge-kit\/\">Open Cartridge Kit<\/a> (not included, sold separately) is en easy start to make your own electrowetting cartridges for topless digital microfluidic applications using readily available materials.<br \/>\n3. The <a href=\"https:\/\/gaudishop.ch\/index.php\/product\/opendrop-v4-cartridge-1x\/\">OpenDrop V4 Cartridge<\/a> (not included, sold separately) is a newly developed, fully functional cartridge capable of &#8220;move, mix, split and reservoir dispensing&#8221;. The 14\u00d78 electrode array and 4 reservoirs are laminated with a 15um ETFE foil, hydrophobic coating and ITO top cover.<br \/>\n4. With the Temperature Controller Option, the <a href=\"https:\/\/gaudishop.ch\/index.php\/product\/opendrop-v4-cartridge-heated-pads\/\">OpenDrop V4 Cartridge with Heated Pads <\/a>(not included, sold separately) can be used and 3 zones on the electrode board can be individually temperature controlled.<\/p>\n<p><strong>Programming<\/strong><br \/>\nThe OpenDrop V4 can be operated standalone and droplets can be moved through the built in joystick. A control software to program sequences of patterns from a computer is available as a free download. The board is also compatible with Adafruit Feather M0 controller boards and can be reprogrammed through the free <a href=\"http:\/\/arduino.cc\/en\/Guide\/HomePage\">Arduino IDE<\/a> for custom specific applications.\u00a0 A sample code with the instruction to activate electrodes can be found on the <a href=\"https:\/\/github.com\/GaudiLabs\/OpenDrop\">OpenDrop GitHub<\/a>.<\/p>\n<p><strong>Features:<\/strong><\/p>\n<ul>\n<li>Modular Cartridge System<\/li>\n<li>Connector to connect electrode board with up to 128 channels<\/li>\n<li>Gold coated 14\u00d78 electrodes array, 2.75 mm x 2.75 mm in size, 4mil gaps<\/li>\n<li>Reservoirs \u2013 the new electrode array features 4 CT-type reservoirs<\/li>\n<li>AC and DC voltage generated on the device form USB power.
