• DEVICE Mode – Connect the debug mini-B USB cable to port J1 and then
connect the starter kit to the host by using a cable with a Type-B micro-connector
to the starter kit’s micro-A/B port J5, which is located on the bottom of the board.
The other end of the cable must have a Type-A connector. Connect the Type-A
connector to a USB host. Jumper JP1 should be removed.

• OTG Mode – Connect the starter kit to the OTG device using an OTG micro-A/B
cable to the micro-A/B port J5, which is located on the bottom side of the board.
The starter kit provides an on-board power supply capable of providing 120 mA
Max. This supply is controlled by the PIC32MZ2048ECH144 device. Jumper JP1
should be removed.

Switches
Push button switches provide the following functionality:
• SW1: Active-low switch connected to RB12
• SW2: Active-low switch connected to RB13
• SW3: Active-low switch connected to RB14
The switches do not have any debounce circuitry and require internal pull-up resistors;
this enables the user to investigate software debounce techniques. When Idle, the
switches are pulled high (+3.3V), and they are grounded when pressed.

LEDs
The RH0 through RH2 LEDs are connected to PORTH of the processor. The PORTH
pins are set high to light the LEDs.

Oscillator Options
A 24 MHz oscillator circuit (Y4) is connected to the on-board microcontroller. This
oscillator circuit functions as the controller’s primary oscillator. Depending on which is
populated on the starter kit board, a 24 MHz crystal (Y1) may be used instead of Y4.

Use of an external crystal is required to develop USB applications. The USB specification
dictates a frequency tolerance of ±0.25% for high speed. Non-USB applications can use
the internal oscillators.

The starter kit also has provisions for an external secondary 32 kHz oscillator (Y2);
however, this is not populated. A suitable oscillator, the ECS-3X8, can be obtained from
Digi-Key: P/N - X801-ND CMR200TB32.768KDZFTR.

The PIC24FJ256GB106 is independently clocked and has its own 12 MHz crystal.

168-pin Modular Expansion Connector
The PIC32MZ Embedded Connectivity (EC) Starter Kit is designed with a 168-pin
modular expansion interface, which allows the board to provide basic generic func-
tionality and easy extendability to new technologies as they become available.
