JUMPER DESCRIPTION
J1
When 1-2 are shorted – RTS is connected to terminal pin RTS/DTR.
When 2-3 are shorted – DTR is connected to terminal pin RTS/DTR.
Default state is 1-2.
LED_J
When this jumper is open – LED is not connected.
When this jumper is closed – LED is connected to pin1 (T0/PB0) of the
Microcontroller.
Default state is closed.
3.3V
When this jumper is open – LM317 output is 5V DC.
When this jumper is closed – LM317 output is 3.3V DC.
Default state is open.
WARNINGS!!!
1. The 3.3V jumper selects the power voltage to be 5V (open) or 3.3V (closed).
MAX232 can operate only at 5V power supply so if you are working with 3.3V you should replace it
with MAX3232 which works at 3.3V power supply.
2. If you want to operate with 3,3V power supply, remove R6 resistor.
