1 OVERVIEW
NuMaker Uni is an IoT or wearable application development board based on NuMicro®
NANO100NE3BN. The start kit enables quick development, prototype evaluation, and creation of
innovative designs for users. The kit also includes complete source-code examples, which helps
users to build target C code applications quickly.
The NuMaker Uni has built in many components such as a Gyro sensor, a Wi-Fi Module, and a
Bluetooth Module. By these components, developers can create new applications and working
prototypes easily. It also allows users to extend its hardware, like servo motor, LED and
EEPROM. The NuMaker Uni is suitable for a variety of IoT or wearable applications. Developers
can implement applications for IoT such as home security, gas leak warning, smart remote
controller, humidity and temperature monitor, and self-balancing scooter, multicopter. Developers
can also implement applications for wearables such as pedometer, oximeter, heart rate monitor,
electrocardiography (ECG), and smartband.
The NANO100NE3BN is an ultra-low power 32-bit microcontroller embedded with ARM®Cortex®-
M0 core operated at a wide voltage range from 1.8V to 3.6V and runs up to 42 MHz frequency.
Features1.1 The NuMaker Uni offers the following features:
IR Transmitter
IR Receiver
3-axis accelerometer and 3-axis Gyro sensor (MPU6500)
Temperature-Humidity sensor (HTU21D)
ESP-03 –802.11b/g/n Wi-Fi Module
BB2710-29 –Dual Mode Bluetooth Module

2 INTRODUCTION TO NUMAKER UNI
The NuMaker Uni uses the NANO100NE3BN as the target microcontroller. Figure 2-1 shows the
NuMaker Uni board.
Figure 2-1 NuMaker Uni Board
The NuMaker Uni supports the Nu-Link ICE Adaptor, and uses In-Circuit Programming (ICP)
mode based on the SWD interface. The uvNuMicro® ICP Programming Tool can be used for
developers to develop their software and program the MCU. The NuMaker Uni also supports third
party development tools, such as Keil RVMDK, and IAR EWARM.
The NANO100NE3BN used by the NuMaker Uni can run up to 42MHz, and support 3.7V to 5V
DC connector for 3.7V Lithium battery or 5V power supply. It includes Red/Geen/Blue LED, an
Infrared transmitter and infrared receiver, 3-axis accelerometer & 3-axis gyroscope (MPU6500), a
temperature & humidity sensor (HTU21D), a 802.11b/g/n Wi-Fi module (ESP-03) which supports
TCP, UDP server & client, AP or Station mode, and AT command, and a dual mode Bluetooth 3.0
module (BB2710-29) which supports SPP and GATT profile, and AT command.

3 INTRODUCTION TO NU-LINK MINI
The Nu-Link Mini is a Debug Adaptor which connects the USB port of your PC to your target system
(via Serial Wired Debug Port) and allows you to program and debug embedded programs on the
target hardware. To use the Nu-Link Mini Debug adaptor with Keil or IAR, please refer to “Nuvoton
NuMicro®IAR ICE Driver User Manual” or Nuvoton NuMicro®Keil ICE Driver User Manual” for details.

Figure 5-3 Blue LED Turns On
After the Nu-Link Mini is connected to PC, PC will start searching USB device, and it will be
recognized as USB ICE shown in the peripheral device window of control panel. Also, the Nu-
Link Mini LED will turn on to indicate the power is supplied from PC.
The Blue LED turns on as shown in Figure 5-3 after the connection from NuMaker Uni to PC
through Nu-Link Mini. It means the R/G/B LED, the Bluetooth Module, the Wi-Fi Module, and
the I2C module is ready to use. For more detail please refer to 6.1.1.
