I ordered the white display. The display works (now) fine: it shows a bright and well readable picture and operates even with a 2.8V power supply.However, I took me long to figure out how to operate it in I2C mode:the following modifications are necessary:- remove R4 and put the resistor into R3 position- put in 0 Ohm resistors (=bridges) on R5 and R7 positions- pin DC selects the I2C address: pulling it via 10k resistor to Vcc gives address "3D", pulling it to GND gives address "3C"- you MUST connect the RES pin such, that there is a reset after power-on (via arduino res-pin or by connecting to RC circuit: 4.7µF to GND and 10k to Vcc). If you don't do, the display stays dead.=> all this info is missing on the sellers page! Only resistors R13, R15 and r17 are mentioned, but they don't exist on the module.Seller should add documentation and maybe offer this (otherwise very good) display in 2 dedicated configurations for either (i) SPI or (ii) I2C operation.
