Quantity:

This USB-to-I²C adapter enables a PC or other USB host to act as the controller on an I²C bus, reading and writing data from I²C target devices connected to the bus. It supports clock stretching and I²C clock speeds in excess of 1 MHz. The adapter features complete galvanic isolation between the USB and I²C sides, which prevents unexpected current flow between the two sides and protects the computer and its USB ports from destructive voltages on the I²C bus. This version delivers isolated power to the I²C side at 5V or 3.3V (selectable by an integrated switch with the state latched at start-up).

It supports clock stretching and I²C clock speeds in excess of 1 MHz. The adapter features complete galvanic isolation between the USB and I²C sides, which prevents unexpected current flow between the two sides and protects the computer and its USB ports from destructive voltages on the I²C bus. This version does not deliver USB power to the I²C bus, so a voltage of 2.25 V to 5.5 V must be supplied on the I²C side.

Quantity:

This module enables galvanically isolated bidirectional I²C communication between two devices while supplying regulated, isolated power to the target. The bidirectionality applies to both SDA and SCL, which allows for clock stretching. The output voltage is set to 5 V out by default and can be changed to 3.3 V through a selection pin. This version has JST SH-style 4-pin connectors that are compatible with Sparkfun’s Qwiic and Adafruit’s STEMMA QT. Power specs:

Input voltage Output voltage Max output current
4.5 V to 5.5 V 5 V (default) or 3.3 V (selectable) 200 mA
3 V to 3.6 V 3.3 V 75 mA

Quantity:

This solid state relay/switch board provides a way to make and break an electrical connection based on a 2.7 V to 40 V input signal. Its electrically isolated output makes it suitable for various applications where mechanical relays are traditionally used, while its semiconductor-based design avoids many of a mechanical relay’s disadvantages. This version can switch up to 7 A of current at voltages up to 60 V (absolute maximum).
