Hello everyone!
So I was about to buy the Aardvark I2C/SPI Host Adapter; however before heading to the shop. I made a little and quick research and I found the following tool: Binho Nova: Multi-Protocol USB Host Adapter.
I'm impressed with Binho Nova specifications (higher interface frequencies for SPI and I2C than Aardvark, plus UART, 1-wirea nd ATMEL SWI interfaces support).
I would like to know if anyone of you had the opportunity to work with these two tools and could share his/her opinion?
BTW, the Binho nova is ~30% cheaper that the Aardvark in my region.

I'll list the key features for both tools:
Aardvark I2C/SPI Host Adapter ● I2C master and slave up to 800 kHz† ● I2C multi-master support ● SPI master up to 8 MHz ● SPI slave up to 4 MHz ● GPIO with selectable pins
The Aardvark I2C/SPI Host Adapter is compatible with: ● Display Data Channel (DDC) ● System Management Bus (SMBus) ● Power Management Bus (PMBus) ● Smart Battery Bus (SBBus) ● ntelligent Platform Management Interface (IPMI) ● Two-Wire Interface (TWI)
| Binho Nova Multi-Protocol USB Host Adapter ● Support for SPI @ 12MHz max clock ● Support for I2C @ 3.4MHz max clock ● Support for UART @ 1000000 max baud ● Support for Dallas 1-Wire ● Support for Atmel Single-Wire Interface ● Provides 3v3 and VUSB power rails ● 1 x DAC Output, 5 x ADC Inputs ● GPIO / Interrupt / PWM Support ● Programmable RGB Status LED ● Field-Upgradeable Device Firmware ● Cross-platform Support for Windows, Mac, Linux ● Robust, low-profile Aluminum Enclosure ● USB Type-C Connector
