In our opinion, the only thing the Raspberry Pi 3 and Pi2 is truly lacking is an I2C port. (Of course you may have guessed by looking at our product offerings that we are admittedly a little biased. No worries.)
The TOUTPI2 is a non-invasive I2C adapter complete with level shifter providing you with a 5V I2C port for use with any of our I2C devices.
The I2C port points outward toward the outside edge of the board, and terminates directly above the HDMI port. The TOUTPI2 does not consume the 40-pin expansion port, as it is equipped with a pass-through connector, freeing the 40-pin connector for other purposes, making it a truly non-invasive design.
Companion - Purchasing Limits Apply
These products are sold at a low price in an effort to help our customers gain connectivity to our product line. Companion products are intended to be paired and used with other products we manufacture, as they perform no useful function on their own. Any orders that contain only companion products will be canceled to prevent short supply. Most notably, products found on our web site for $5.95 or lower are typically defined as companion products (though there are a few exceptions).
As a general guideline, we allow one companion product to be purchased for every device with a silicon chip that has an I²C start address, with a maximum of 3 companion products of a single part number. For instance, you can purchase a Raspberry Pi I²C adapter and a Temperature sensor without any problems. You can purchase 3 I²C adapters and 3 temperature sensors without any problems. You can purchase 3 I²C adapters and 20 temperature sensors, but no more than 3 I²C adapters of the same part number.
- We will allow up to ONE companion product without any silicon based controllers per order.
- We have placed a maximum quantity limit of 3 pieces per companion part number.
Please help us balance the production costs of our low-cost devices and support our company by purchasing devices to go with our companion products, this is the only way we can stay in business.
