MAC32WLE5
Explore the highlights

Built on the STM32WLE5 — an Arm Cortex-M4 and the LoRa radio in a single silicon die, so your product needs one part where designs used to need two.
The full transmit power the silicon offers, across the sub-GHz bands used worldwide.
Single-digit microamp deep sleep from the same platform that powers our ten-year battery sensors — your battery budget starts from the right place.
The same module inside Macnman's shipping sensors and dataloggers — field-tested before it ever reaches your design.
In plain terms
What Is a LoRaWAN Module?
The short answer
A LoRaWAN module is a small radio board that a manufacturer solders into its own product to give it long-range, low-power connectivity. It carries the LoRa transceiver, a microcontroller and the LoRaWAN® protocol stack in one part, so the product team writes its application without designing the radio circuit from scratch.

MAC32WLE5
The MAC32WLE5 is built on the STM32WLE5, which puts an Arm Cortex-M4 and the LoRa radio on a single chip. It is the same module inside Macnman's own sensors and dataloggers, so it is field-tested before it reaches your design.
An STM32WLE5 system-on-chip: an Arm Cortex-M4 with 256 kB of flash and 64 kB of RAM, clocked at up to 48 MHz.
Up to +22 dBm on the sub-GHz ISM bands, for LoRaWAN® or LoRa point-to-point links.
Runs from 1.8 V to 3.6 V and draws less than 3 µA in sleep.
21 I/O pins with a 12-bit ADC, and UART, SPI and I2C buses.
A 15 mm × 15 mm surface-mount module with a pad for an external antenna.
Also described as a LoRa module, an STM32WLE5 module or a LoRaWAN OEM module.
