ERC1602-4 I2C 16x2 LCD case for fischertechnik

thingiverse

Conventional 16x2 character LCD displays with hd44870 controllers are enormous in size. They grow even larger when a PCF8574-based I2C module is attached to their backside. Buydisplay.com sells the EastRising ERC1602-4 LCD series featuring a chip-on-glass (COG) ST7032 I2C controller, which significantly reduces its compactness. This results in a sleek and sexy 75x30x15 mm fischertechnik-compatible case. Its I2C connector is compatible with ftDuino and ft TX connectors. Connectivity is achieved through a simple perfboard PCB with the following connections: * Pull up RESET (pin 1) using a 4,7k resistor * Pin 9 to VDD and pin 10 to GND for I2C mode * Never forget a capacitor with correct polarity between pins 11 and 12, or display errors will occur; I used 1µF * The 47 ohm LED resistor is suitable for VDD = 3,3V; however, with 5V you'll need a larger one * SCL, SDA, GND, and VDD for I2C If you require more information, please use the comment section or contact me directly.
