Development Board
RV-3049-C2
RV-3029-C2
The RV-3029-C2 is soldered onto the Development Board.
Every pin is either accessible at test pins 1 – 10 or at the test vias situated around the device.
The following passive components are already soldered on the Board:
C1
10 nF
Decoupling capacitor between V
SS
and V
DD
R1
330 Ω
current limiting resistor for LED
LED green
Supply, current consumption of the LED has to be considered
R2
10 k Ω
Pull-up resistor INT to V
DD
R3
10 k Ω
Protection resistors to prevent short-circuit between external CLKOE signal and jumper.
