In a blog post from a few years ago, [Peter Molnar] explains in detail how to wire up a physical adapter to add a USB-connected I2C interface to a system. At its core is the ATtiny85 AVR-based MCU ...

An RP2040 based adaptation of the i2c-tiny-usb. "Attach any I2C client chip (thermo sensors, AD converter, displays, relays driver, ...) to your PC via USB ... quick, easy and cheap! Drivers for Linux ...

The driver can be used with CH341A USB to UART/I2C/SPI adapter boards to connect I2C devices to a Linux host. The I2C interface driver was initially derived from CH341 I2C driver from Tse Lun Bien and ...

We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years ... 4 has six SPI controllers, six I2C controllers, and six UARTs ...

It features the AP33772S USB-C PD3.1 sink controller from Diodes Incorporated ... The PicoPD Pro is open-source, with hardware schematics, Arduino code (mostly for the AP33772S control over I2C), and ...
