This device is a USB to SPI interface (master mode). It 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 can autonomously interpret data coming from any external SPI board and expose measures as if they were coming from a Yoctopuce sensor, with all the inherent advantages: unique identifier, polling, callbacks, data logger. Note that this device does not work with applications designed to use a COM port, it is designed to be used with Yoctopuce API only.
The device can also analyze a bidirectional SPIcommunication between two tiers without interference (listening two both directions simultaneously).
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 enclosures to be ordered separately.
