Arduino-Compatible Headers
J9, J13, J12 and J10 are the Arduino headers available in the CYW954907AEVAL1F EVK.
Table 4-8
shows the pinout of the Arduino Header. Note the following points while connecting an Arduino
shield to the board:
■
5V pin of Header (J9) is not connected to the board.
■
The maximum current that an Arduino shield can sink from the board depends on the application
that is running. In general, 100 mA is the worst-case scenario.
■
The Arduino Analog reference is connected to the 3V3 (3.3V) power supply through R21 which is
not populated by default. In other words, the analog reference is not driven by default.
■
An external ADC attached to CYW54907 helps to achieve Analog functionality on the Arduino
headers.
