SC137 is an I2C bus master module designed for the RC2014 bus.

An I2C bus master is a device that can control I2C slave devices on an I2C bus. This makes the module useful for interfacing with external electronics. In this case, the module generates the I2C bus signals using big-bang code.

The main features of this design are:

• I2C bus master
• LEDs to indicate activity on the SCL and SDA lines
• Simple access using a dedicated I/O port
• Two connections for I2C bus devices
• Supports I2C clock stretching
• Low profile RC2014 style design
