CYW920819M2EVB-01 evaluation kit user guide
Hardware
Power supply options can be selected via jumper settings on J7, J8, and J16. See
, and
for the different jumper settings for these jumpers. Resistors R25 and R21 are pull-up resistors for the
I
2
C lines to the ambient light sensor i.e., SCL and SDA. Note that J19 (PERIPH ENABLE) should be shorted for any
I
2
C devices to be connected because the pull-up voltages for SCL and SDA are supplied from VDDP. The VPA_BT
selection jumper (J16) applies to evaluation boards that has an internal power amplifier connected to the
Bluetooth® chip and does not apply to CYW920819M2EVB-01 evaluation kit.
