1 OVERVIEW
The NuMaker-IoT-M467 is an evaluation board for Nuvoton NuMicro M467SJHAN, M467KJHAN,
M467JJHAN, M467HJHAN microcontrollers. The NuMaker-IoT-M467 consists of two parts: an M467
target board and an on-board Nu-Link2-Me debugger and programmer. The NuMaker-IoT-M467 is
designed for project evaluation, prototype development and validation with power consumption
monitoring function.
The M467 target board contains a Wi-Fimodule and a CAN FD transceiver for users to develop industrial
IoT applications. Furthermore, the M467 target board is equipped with a thermal sensor and a 6-axis
sensor for quick development.
The M467 target board is based on NuMicro M467HJHAN. For the development flexibility, the M467
target board provides the Arduino UNO compatible headers and the capability of adopting multiple
power supplies. Furthermore, the Nuvoton-designed ammeter connector can measure the power
consumption instantly, which is essential for the prototype evaluation.
In addition, there is an attached on-board debugger and programmer “Nu-Link2-Me”. The Nu-Link2-Me
supports on-chip debugging, online and offline ICP programming via SWD interface. The Nu-Link2-Me
supports virtual COM (VCOM) port for printing debug messages on PC. Besides, the programming
status could be shown on the built-in LEDs. Lastly, the Nu-Link2-Me could be detached from the
evaluation board and become a stand-alone mass production programmer.

3 INTRODUCTION TO NUMICRO IOT PLATFORM
The NuMicro IoT platform provides the cloud services support, tools, and developer ecosystem to make
the creation and deployment of commercial, standards-based IoT solutions possible. As an IoT
resource, the NuMicro IoT platform contains a core, and security, key IoT networking and
communication capability.
The NuMicro IoT platform allows IoT devices to collaborate and communicate with each other on the
basis of transparency. With abstractions API design, the NuMicro IoT platform allows users to focus on
application development, not underlying system complexity.

Note:
1. The Vin input voltage will be converted by voltage regulator UP2 to 5 V. Supplying external power to Vin or J2 or J3 can
provide 5 V to NU1 pin5 (5V) and 3.3 V to NU1 pin4 (3VCC).
2. JP1 external power input only provides voltage to target chip.
3. 0 Ω should be removed from ICEJPR1’s MCUVCC and 1.8 V / 3.3 V / 5 V.
4. 0 Ω should be soldered between ICEJPR2’s ICEVCC and 1.8 V / 3.3 V.
5. The ICE chip voltage should be close to the target chip voltage.
6. -: Unused
