Figure 2From: POSaM: a fast, flexible, open-source, inkjet oligonucleotide synthesizer and microarrayerDiagram of the POSaM. The system uses two PCI-interface input/output boards (MIO-16E and DIO-32HS) and one ethernet-interface servo controller (6K4). Future software revisions will support a second print head, to provide more reagent channels, and the X-axis linear position encoder to increase printing speed.Back to article page
