HD44780 Technical Information for HD44780 LCD Controller 286K
PCF8574 The PCF8574 Mini Board is a quick and easy solution to extending and adding output ports to your control system. The board connects to a standard I2C bus and adds an additional 8 output ports to your system. A total of 8 of these boards can be added to a single I2C bus with each board having a unique address. The PCF8574 Mini Board includes the Philips Semiconductor PCF8574 IC together with selectable pull-up resistors for the I2C Bus. The output connections use a standard IDCC connector, and can be easily connected to external equipment. A set of 3 jumpers are included on the board for address selection. The PCF8574 Mini Board is a great way of extending the number of output points available for your control system. 134K
