32 Bits

High-performance processing unit for the most complex task and high demand applications.



Modulations available

For any Incredible IoT applications.

The Sub-Ghz Radio is a low power radio with a high quality matching filter for operate 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 of 16, 5 mm X 15, 5 mm LGA and comes with a 66 pin out 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.

Challenge-off: Others Module with the WL


High-performance processing unit for the most complex task and high demand applications.

Some of the peripherals:

  • 3x I2C,
  • 2x SPI,
  • 2x U(S)ART,
  • 1x LPUART
  • 2x DMA
  • 7x TIMER of which 3 Ultra-low-power

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.
