CHAPTER 1: INTRODUCTION
Thank you for choosing this general-purpose development board designed and assembled by
Olimex LTD! This document provides a user’s guide for the PIC32-HMZ144 board. As an
overview, this chapter gives the scope of this document and lists the board’s features. The
document’s organization is then detailed.
The PIC32-HMZ144 development board allows code development of applications running on the
PIC32MZ144 processor, manufactured by Microchip Technology Inc from the U.S.A.
PIC32-HMZ144 board is an open-source, open-hardware project and all documents needed to
manufacture the board are available to the customer.
The software code written by Olimex LTD is released under GPL. However, the examples that we
distribute are heavily based on the libraries and projects released by Microchip Technology Inc,
which are non-GPL. Make sure that you are acquainted with Microchip's license agreement before
using, publishing, or distributing any code based on the demo software released by Olimex LTD.
1.1 BOARD FEATURES
PIC32-HMZ144 board features a PIC32MZ2048EFG144 processor. It is one of the most-capable
PIC32 processors ever made and it has a lot of interfaces available (FPU, x UARTs; x SPIs; 5 x
I2Cs; 120 x IO pins; 48-channel ADC; two analog comparators; Ethernet; USB-OTG; JTAG;
TRACE; etc.) The board has several ready-to-use interfaces exposed and available on connectors: a
microSD card connector; mini USB connector (with OTG functionality); ICSP connector for
programming and debugging; UEXT connector for extension modules; user-programmable LED;
user-programmable button; 100 pinholes in two rows for measurements and access to IO processor
pins; etc.
Starting 20th of October 2017 the PIC32MZ2048ECG144 chip was replaced by a
PIC32MZ2048EFG144. The PIC32MZ2048ECG144 was officially declared “not recommneded for
new designs” by Microchip and we decided to switch to the officially suggested replacement. The
chips are pretty much the same except that the new EFG chip has a floating point unit (FPU), better
maximum A/D resolution (12 v 10) and better maximum A/D sample rate (18000KSPS vs
5000KSPS).
The most notable board features are listed below:
PIC32MZ2048EFG144 with 512KB RAM and 2MB flash (PIC32MZ2048ECG144 was
used before)
USB-OTG functionality with mini USB connector
MicroSD card connector
ICSP for debugging and programming
JTAG pins exposed on 0.1" step pins
EXT1 and EXT2 50 pin 0.1" connectors that ease the access to the processor
RESET and USER buttons
PWR and STATUS LEDs
Li-Po battery connector and charger
UEXT connector
Dimensions: (77×52)mm ~ (3×2)mm

1.2 MINIMAL BOARD USE REQUIREMENTS
•Hardware required or programming
In order upload code on the board you would need a PIC32 compatible debugger or programmer.
Older tools might lack support for PIC32 processor. Please ensure your programmer/debugger is
compatible with the PIC32MZ processor family.
The board has no bootloader loaded. You need either a debugger or a programmer tool to upload
software to the board. The on-board ICSP interface is available at a -pin (1× ) 0.1” step connector.
•So tware required or programming
You would need software that supports PIC32MZ family of processors. The most commonly used
tool for software development for PIC32MZ applications is MPLAB X. The most used tool for
binary upload to PIC32MZ is MPLAB IPE. Microchip provides a set of libraries and demo projects
for the PIC32MZ family in their “Harmony Integrated Software Framework”.
Note that MPLAB 8.xx does NOT support PIC32MZ.
•(Optional) hardware to power the board.
The board requires power supply. If your debugger/programmer is not capable of powering the
board via the ICSP connector then you would need either: USB cable (1); or Li-Po battery (2); or
5V external power supply (3).
(1) The USB cable should have male mini USB connector to be able to fit the board's female mini
USB connector.
(2) The battery requires a male DW02R connector (CI0102) to fit in the on-board female DW02R
connector.
(3) There are only pinholes available on the board. You would need wires to establish a connection
between the external power supply (adapter) with the board.
1.3 TARGET MARKET OF THE BOARD
PIC32-HMZ144 would attract PIC enthusiasts and veterans who want to evaluate the features of the
PIC32MZ2048EFG144 processor. Any experience with the development tools required for general-
purpose development of code for boards featuring PIC32MZ boards is a great plus.
The board is not suitable for complete beginners – it lacks a bootloader which means that you can't
upload software via the USB. You need at least a PIC32-compatible programmer with -pin 0.1”
step ICSP connector.
In case you are a complete beginner you might want to start with a board with bootloader, like
PIC32-PINGUINO-OTG or DUINOMITE. You can upload code to such boards via an USB cable.

1.4 ELECTROSTATIC WARNING
The PIC32-HMZ144 board is shipped in protective anti-static packaging. The board must not be
subject to high electrostatic potentials. General practice for working with static sensitive devices
should be applied when working with this board.
The product box includes 4 rubber feet – it is recommended to place them in the holes near the
edges of the board. This way the board would be safe if placed on conductive surfaces!

CHAPTER 5: CONTROL CIRCUITRY
5.1 POWER SUPPLY CIRCUIT
You have options on powering PIC32-HMZ144. You can power the board by providing:
•5V on the mini USB connector
You can power the board from your personal computer via an USB cable; the USB ports of a
personal computer typically provide around 5V of voltage and 500mA of current.
Avoid using USB cables longer than 2 meters. Avoid the cheapest cables with high inner resistance.
•(3.6 – 4.2)V on the Li-Po battery connector
The board can be powered the board from a Li-Po battery with a fitting connector; a Li-Po battery
typically provides between 3. V and 4.2V of voltage.
•3.3V on the ICSP connector
PIC32-HMZ144 can be powered by your debugger (programmer) tool, as long as the tool is capable
of powering targets. You would need to set and enable the powering voltage to 3.3V in the software
options of MPLAB.
•5V to pin 1 o the EXT2 connector
The board can be powered by external power supply (adapter) capable of providing 5V of voltage.
You should connect the 5V wire to pin #1 of EXT2 connector. You also need to connect the ground
wire to pin #2 of the same (EXT2) connector. The names of the pins are printed at the bottom of the
board.
Different methods of powering would lead to different maximum current available. Consider
powering the board with an external power supply connected to EXT2 if you need extra current (in
case you have to power additional hardware via PIC32-HMZ144).
You can have more than one power supply connected at the same time. Note that the board has
built-in battery charger. If you have another power source connected to the board at the same time
as the battery (for example, USB) – the charger circuit would attempt to recharge the battery. This
would raise the current consumption of the whole board.
With no extra peripherals connected, the board's current consumption is about 100mA at 5V when
running the default demo program.

5.2 RESET CIRCUIT
PIC32-HMZ144's reset signal (processor pin #20, “#MCLR”) can be found on the pads of the JTAG
connector (pad #1); on the ICSP connector (connector pin #1); and it is also connect to a button.
The reset circuit of the button consists of RC group R24 – 10kΩ and C35 – 100nF. Serial resistor
R2 – 330Ω is used to prevent fast C35 charge and discharge when PIC32MZ2048 is being
programmed.
Manual reset is possible by the RESET button.
5.3 CLOCK CIRCUIT
Oscillator CD1 24MHz handles the clocks.
Previous hardware revisions used crystals due to the different chip. Make sure to refer to the errata
sheets the chips if you investigating the clocks.

CHAPTER 6: JUMPERS, CONNECTORS AND INTERFACES
In this chapter you will find the description of the jumpers and what signals might be found on the
different connectors.
6.1 JUMPER DESCRIPTION
PIC32-HMZ144 has no re-configurable jumpers.
6.2 INPUT/OUTPUT
User button with name BUT – connected to PIC32MZ's pin #59 (AN7/RB12). BUT can be accessed
via software means.
Reset button with name RST – connected to PIC32MZ's pin #20 (#MCLR).
Status LED (green) with name LED1 – connected to PIC32MZ's pin #45 (EBIRP/RG2). LED1's
behavior can be programmer.
Power supply red LED with name PWR – indicates that 5V power supply is available. Cannot be
programmed.
6.3 EXTERNAL CONNECTOR DESCRIPTION
In this sub-chapter you would find the pinout of the most interfaces. It is also a good practice to
refer to the latest schematic.
6.3.1 ICSP CONNECTOR
The ICSP connector is used for serial programming. It is the place where most common PIC32-
compatible programmers and debuggers are connected. The pins have 0.1'' step. If your
programmer/debugger has only the smaller 0.05'' connector you might need an adapter or you
should use jumper wires.
Pin # Signal name
1 RSTN
2 3.3V
3 GND
4 PGED2
5 PGEC2
6 NC
PGED2 conducts I/O operations for the “Program Data” signal. Serial data for programming.
PGEC2 serves only as input for the “Program Clock” signal. Clock used for transferring the serial
data (output from ICSP, input for the MCU).

6.3.3 UEXT
The 10-pin UEXT connectors are typically mounted on Olimex boards. They pack three common
interfaces in a single connector – UART, I2C and SPI. You can use the UEXT connector to access
this interfaces easier (via jumper wires, for example).
You can also connect expansion modules to the UEXT connectors. More on UEXT might be found
