Configuration Options
(1) Power Supply Selection
Since you'll probably be connecting other things to the Arduino (LEDs, sensors, servos) we recommend using a DC power
supply that can provide at least 1000mA of output current.
IMPORTANT NOTE:
When using the A NHD-FT81x-SHIELD connected to an EVE2 TFT Module, a DC power
supply should always be connected to the Arduino’s DC input. This is due to the current limitations of the USB input on the
Arduino.
(2) Arduino I/O Configuration (SPI)
On the NHD-FT81x-SHIELD, six solder jumpers (SJ1, SJ2, SJ3, SJ4, SJ5, and SJ6) have been added to provide flexibility to the
Users’ Arduino selection.
Solder Jumpers SJ1, SJ2, and SJ3 enable the SPI lines on the ICSP header. The MISO, MOSI, and SCK lines are available in a
consistent physical location on the ICSP header (Solder connections fitted by default).
Solder Jumpers SJ4, SJ5, and SJ6 enable the SPI lines on the Arduino Uno’s Digital header. A number of clones do not
include the ICSP header, and therefore this configuration is required to be compatible.
