This device is a USB to SPI interface (master mode). Il can handle the 4 standard SPI modes, and both bit encoding directions. It does not require a driver and does not install a virtual COM port.
It is able to autonomously interpret data coming from any external SPI board and expose measures as if they would come from a Yoctopuce sensor, with all inherent advantages: unique identifier, polling, callbacks, datalogger. Note that this device will not work with applications designed to use a COM port, it is designed to be used with Yoctopuce API only.
If needed, the device can also provide a 3.3V or 5V voltage source to power the external serial board. The 3.3V source can provide up to 200mA. The voltage used for SPI signals can be selected independently of the source voltage.
USB cables and enclosure to be ordered separately.
