2.3 Protocol Select Jumpers
display module between RS-232, TTL and I
with solder jumps on the 232 jumpers. In order to place the display module in I
remove the solder jumps from the 232 jumpers and then place them on the I2C jumpers. The display will
now be in I
to change the display to TTL mode, simply remove the zero ohm resistors from the 232 or I
solder them to the TTL jumpers.
