Create Incredible IoT Products

MAMWLExx is a new low power radio module (LoRaWAN Compliant) with a high-performance processing unit 32 Bits ARM M4 for the most complex task and high demand applications.

The module comes with a size of 128K Flash and 64K RAM which can be used for important computing calculations and to embed the biggest software applications.

Create a device for any kind of applications, from smart metering to automation control systems, MAMWLExx is the perfect core for your product.

The Module

The Sub-Ghz Radio is a low power radio with a high-quality matching filter for operating in the band of 868 Mhz and 915 Mhz. The Sub-Ghz Radio is equipped with two high-performance power amplifier to transmit up to +22dBm and the power can be programmed with a step of 1 dB within 32 steps. A high-quality TCXO 32 Mhz guarantee great stability during transmission.

Small Size Big Resources

The size of MAMWLExx is about 16, 5 mm X 15, 5 mm LGA and comes with a 66 pinout to bring all the functionality and rich peripherals of the STM32WLEx.

The pin-out is designed to use different peripherals at the same time using different protocols like I2C, SPI, LPUART, USART. The module has 12 multiplexed pins for a 12 bit (up to 16 bits) SAR ADC with DMA controllers, 12 bits DAC, 2 ultra-low-power comparator, multiple timers, and independent watchdog.

Easy Integration in your design

The MAMWLExx module is designed to be easily integrated into any PCB offering two assembly variants. One with a U.Fl coaxial connector on the top of the package that can be directly plugged into the antenna through a pigtail, saving space on the mainboard. The other variants, that outputs the RF signal on a 50 Ohm pin, fits you if you wish to create your own antenna design.
