The boost converter IC used in the manufacturing of these displays has been discontinued by the IC manufacturer. This IC has been replaced by a new boost converter with a lower maximum input voltage. This change will only affect customers using jumper option #1 to power the boost converter separately from the display. The previous voltage range for BC_VDD was 3V – 12V. The new voltage range for BC_VDD is 3V – 5.5V.
This change will not affect customers who are using the default jumper setting or jumper option #2.
The new displays will be labeled with a different revision control number on the back of the PCB, underneath the flex cable. See example below.
