1.3. Jumper position description

Two jumpers are present on the board:

• Jumper located in ST1 allows customer to use either the thermistor populated 6 pin FPC (i.e FPC-A-10,

FPC-A-14 or FPC-A-16) or the thermistor located on the board. To use thermistor on the flex, please

set the jumper between pin 1 and 2 as shown in the picture below:

To use thermistor located on the board, please set the jumper between pin 2 and 3.

• Jumper located in ST2 allows customer to use or bypass serial 5kΩ resistor on the COM output of the

Maxim driver. When the jumper is plugged in, the resistor is bypassed. As a reminder this resistor is

recommended when driving A-39N0 lens.

1.4. Control of the board

Refer to MAX14574 datasheet for any information about driver communication protocol.
