I was asked if MCP9008 Temperature sensor can be replaced with the cheaper and widely available LM75 one.
The answer is YES, it can be done without any problems, actually they can share same slot on CBDB Dev Board without any hardware changes as pin compatible, just choose your desired I2C address with the A0, A1, A2 pins.
