EI2C: Enhanced I2C Interface Card

The Enhanced I2C Interface card (EI2C) lets you connect any I2C integrated circuit to your robot or other automation. The card has a prototyping area as well as pads for both TSSOP and SSOP surface mount chips.

 

Features: - Easily connects to most I2C chips - Prototyping area as well as TSSOP and SSOP pads - 5 or 3.3 volt compatible - Uses the ESPI 7474 circuit for reliable operation

The EI2C card must be paired with the "ei2c" peripheral and driver.

 

Hardware:

The schematic and layout of the EI2C are shown below. The Eagle schematic and board files are available here: ei2c.sch and ei2c.brd. The bill-of-materials is available here: ei2c.txt.
