CAUTION: Bright GREEN version require 9v PowerSupply

This is a big 4x 1.2 inch 7-segment LED display module that can display standard 4 digit in format of clock / temperature. LED control is done over I2C using the HT16K33 interface.

Change the I2C address from a backside W0, W1 or W2 solder jumper. Jumper is shorted with solder, that sets the address. W0 sets the lowest bit with a value of 1, W1 sets the middle bit with a value of 2 and W2 sets the high bit with a value of 4. The final address is 0x70 + W2 + W1 + W0. For example, if W2 is shorted and A0 is shorted, the address is 0x70 + 4 + 1 = 0x75. If only W1 is shorted, the address is 0x70 + 2 = 0x72
