Intel Cyclone 10 FPGA and STM32H7 MCU combined to create USB2IO high-speed interface explorer

Electronic designers and hardware hackers may be interested in a new USB2IO high-speed interface explorer tool combines the Intel Cyclone 10 FPGA and STM32H7 MCU. The STM32 microcontroller handles the interface with the host computer over USB and manages the FPGA configuration/data gathering. The new piece of hardware is now available to purchase from online stores such as Amazon priced at around $520 or roughly £380.

Possible applications for the USB2IO high-speed interface explorer include :

– Communication with other electronic devices using I2C, SPI (master only for now), I2S (audio recording or playback), PDM microphone interface, USART, RS485 (via TI SN75HVD11D transceiver), CAN 2.0B bus, MDIO, camera interface…
– 16-channel waveform/pattern generator via 16-pin GPIO interface
– 8-LVDS pairs available
– 1A max programmable LDO with voltage range 1.8V – 3.3V designed for:
– Powering an external device
– Using the same voltage for powering an I/O interface
– Automatic electronic functional testing (USB2IO is able to play various scenarios)
