SCA3000 DEMO KIT User Manual Hardware The CMA3000 DEMO KIT USB interface board (black PWB) and CMA3000 PWB (green PWB) are shown in Figure 1. The USB interface card converts the USB interface to SPI or I C interface. CMA3000 sensor is soldered on PWB which is connected to interface board. - Page 5 Selected sensor type and GUI software version number. Averaging ON / OFF, number of samples for averaging.
