Sangaboard v5


The latest motor control board for the OpenFlexure Microscope. Can control up to 4 unipolar stepper motors (1 extra for advanced uses such as moving illumination), with 2 high current PWM channels to control illumination (or heating) and a constant current driver for LEDs. It comes fully assembled with a stackable pin header for connecting to the Raspberry Pi. Manufactured in beautiful purple PCB with ENIG surface finish (green photo shows an earlier development version). The optional illumination kits add everything not printed needed for the OFM condenser, see the illumination kit page for more details. A heatsink might be needed when using high-power LEDs (e.g. for fluorescence), there is a heatsink kit available with 2 adhesive heatsinks and a thermal pad.
