MAMWLExx Radio Modules

Move-X's MAMWLExx is a low-power, LoRaWAN radio module based on the STM32WLEx microcontroller from STMicroelectronics. It is powered by a 32-bit Arm® Cortex®-M4 with a clock frequency of up to 48 MHz and it is paired with up to 64 kB SRAM and 256 kB Flash. The module embeds a low-power sub-GHz radio for LoRa®, (G)FSK, (G)MSK, and BPSK in the 868 MHz to 915 MHz band (with up to +22 dBm output power), two on-board power amplifiers for maximizing power efficiency at different TX power (programmable with a step of 1 dB within 32 steps), and a high-quality 32 MHz TCXO and RF matching network to guarantee great stability during transmission.

The MAMWLExx module is designed to be easily integrated into any PCB offering the following assembly variants: antenna connection through on-board u.Fl coaxial connector, with no need to deal with RF signals on the application PCB, or antenna connection through 50 Ohm pin, for design creations such as PCB antennas, SMA connectors, etc.

With 37 GPIOs, a small package (15.5 mm by 16.5 mm LGA), and a high number of peripherals, the MAMWLE is designed for any application board. It offers digital interfaces of I²C, SPI, I²S, LPUART, USART 12-channels ADC with 12-bit (up to 16-bits), SAR ADC, a complete set of low power comparators and timers, DMA, 12-bit DAC, and watchdog. Thanks to the flexible pinout, those features can be used simultaneously and multiplexed to optimize PCB routing.
