Evaluates: MAXQ1065

MAXQ1065 Evaluation Kit

Arduino Uno-Compatible Boards

The MAXQ1065 socket board also provides four Arduino-

compatible connectors (JH1, JH2, JH4, and JH5) that

can be used to install Arduino motherboards, such as the

Maxim MAX3265MBED development platform, from the

bottom side of the board. The following steps can be used

to properly set up the MAXQ1065 socket board with an

Arduino-compatible platform:

1) Ensure that the Arduino mother board is powered off.

2) Connect the MAXQ1065 socket board on top of the

Arduino motherboard.

3) Adjust the VDD SEL switch (SW1) according to the

Arduino motherboard’s voltage requirements.

4) Power on the Arduino motherboard.

5) Do not use the USB cable.

Custom Motherboards

In the absence of an Arduino Uno board, the Arduino-

compatible connectors (JH1, JH2, JH4, and JH5) can

also be used for wiring up a custom motherboard to the

MAXQ1065 socket board. Each connector has its pinout

on the silkscreen for reference. The socket board sup-

ports custom motherboards operating in a 1.8V range

through the JH1 connector’s 1V8 pin (pin 1). The VDD

SEL switch (SW1) must be configured to 1.8V when

using a 1.8V motherboard to ensure proper operation of

the socket board. Regardless of its operating voltage, a

5V power supply must be provided from the host moth-

erboard through the JH1 connector’s 5V pin (pin 5) to

ensure proper operation of the socket board.

Hardware Settings

See Table 1, Table 2, and Table 3 for specific details on

each of the MAXQ1065 socket board’s hardware con-

figuration settings.
