3.5.2 JP3: Flat Panel Voltage Select

This jumper selects the supply voltage for the flat panel.
WARNING! Make sure you have selected the correct voltage before connecting the panel. Flat
panels are notoriously sensitive to--and are often irreparably damaged by--incorrect voltages.

3.5.3 JP4: Flat Panel Data Voltage Select

Type: 3-post header, 2mm
This jumper selects the voltage of the data signals for the flat panel display.
Important: These jumpers are set at the factory and cannot be changed by the user. Damage to the
panel drivers may occur if this jumper setting is changed.
Hint: Some 5V panels will run correctly with 3.3V data.

3.5.4 J7: Flat Panel VEE Select

Type: 4-post header, 2mm
This jumper selects the VEE voltage for the flat panel. Note that VEE is installed only as an
option and is not installed on all Bitsy boards.
WARNING! Make sure you have selected the correct voltage before connecting the panel. Flat
panels are sensitive to--and are often irreparably damaged by--incorrect voltages.

3.6 Connector Pinouts

The following tables describe connector pinouts and the type of connector. At least one pin of
every connector is labeled on the Bitsy. Double-row headers on the board are
all numbered as shown in the figure to the right.
For information about the location of the connectors on the Bitsy, refer to
