Move-X MAMWLE-xx Low Power Radio Module

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

The MAMWLE-xx Module supports a wide array of peripherals using protocols such as I2C, SPI, LPUART, and USART. The Module has 12 multiplexed pins for a 12-bit (up to 16-bit) SAR ADC with DMA controllers, 12-bit DAC, two ultra-low-power comparators, multiple timers, and an independent watchdog timer.

The Move-X MAMWLE-xx Low Power Radio Module is offered in a compact 16.5mm x 15.5mm Land Grid Array (LGA) package.
