OVERVIEW
Th
e
NuMaker-LoRaD470/868/915-M252 evaluation board, hereafter referred to as NuMaker-LoRaD-
M252, is used to implement LoRa ecosystem device design for LoRa 915 MHz, 868 MHz, and 470 MHz
frequency band, respectively. The NuMaker-LoRaD-M252 consists of two parts: an M252 target board
and an on-board Nu-Link2-Me debugger and programmer. The NuMaker-LoRaD-M252 is designed for
project evaluation, prototype development and validation with power consumption monitoring function
for LoRa application.
The M252 target board is based on NuMicro
M252KG6AE. For the development flexibility, the M252
target board provides the extension connectors of M252KG6AE, LoRa module, 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
LoRa 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.
