J1 allows P6 of the TCA6507 to
connect to an off-board load without the need to desolder LED D5. If the user
wants to use the on-board LED, jumper J1 must be installed.
C1 and C2 are installed by the
user to measure the consequences of varying parasitic capacitances.
The EVM does not come
with these capacitors installed.
R8, R9, R10, and R11 are
replaceable if the user wants to test different pull-up resistors.
