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, 6 x UARTs; 6 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 6 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 for 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 6-pin (1×6) 0.1” step connector.
• Software required for 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 generalpurpose 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 6-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!
