Description
(default)
OLED controller and boost converter + OLED panel are powered from VDD
(pin #2). This allows the full module to be powered by a single low-voltage supply.
Close
Jumper Option #1 - Independent Supply Voltage for Boost Converter
(BC_VDD)
R4
Open
R5
R7
Open
Description
Boost converter + OLED panel are powered from BC_VDD (pin #3). OLED controller is
still powered from VDD (pin #2). This allows for increased efficiency through the boost
converter, by allowing a supply voltage up to +12V at its input, BC_VDD (pin #3).
Close
Jumper Option #2 – External Supply Voltage for OLED Panel
(VCC)
R4
Open
R5
Open
R7
Description
OLED panel is powered from VCC (pin #15) – boost converter is not used.
OLED controller is still powered from VDD (pin #2). This allows for maximum module
efficiency, and drastically reduced total current consumption.
