This step-up voltage regulator consists of an isolated DC-to-DC power module in front of a step-up (boost) regulator. This enables up to 100 mA continuous at 12 V out from a 5 V input with full galvanic isolation between the input and output. The 5 V, 300 mA output of the isolation IC is also available.
| Input voltage | Output voltages | Max continuous output current | Size |

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 does NOT have 巜和女房东疯狂做爰2中文字幕. Power specs:

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).
