2 Product Concept
2.1 General Description
WSL05-A0 module is a low-power, high-performance LoRaWAN module, which integrates
LoRaWANTM protocol stack internally and complies with LoRaWANTM Specification 1.0.2
Class A \ C application standard.
WSL05-A0 module uses serial interface (UART or SPI) to exchange data with user devices.
It has significant features such as automatic connection to the network and saving session
context, which is convenient for users to quickly access the network and wireless data
transmission services.
WSL05-A0 module supports the secondary development function (open CPU function),
which can write and run the client’s code, enabling users to implement their own specific
applications without the need for an external MCU, saving costs for users and providing
lower power consumption.
It has several options that support different bands, the following table shows the frequency
bands of different variants.
With ultra-low power consumption, extensive coverage and simple peripheral circuits
features, WSL05-A0 facilitates development and is well applicable to IoT applications that
requires low rate and low power consumption. It adopts SMT package and its dimensions
are 22 mm x 14 mm x 3.2 mm, which make it very suitable for size-constrained applications
with tight space.
The hardware resources and functions which is available to customers include:
 UART interface, used for data communication, debugging and
software upgrade.
 Provide 20K bytes of Flash space for user's secondary
development program.
 Status indication interface supports NET_LIGHT (network
indicator) and RESET function.
