Designed to reduce BOM and optimise supply chain and certification time, the Move-X MAMWLE is a low-power, LoRaWAN-compliant radio module based on a powerful 32-bit ARM Cortex-M4 processor with clock frequency up to 48 MHz. Paired with up to 64 kB SRAM and 256 kB Flash, it is more than suitable for the most demanding tasks, making it the perfect core for devices in many applications, from smart metering, parking sensors, and automation control systems, to many more.
If this sounds familiar from my RAKwireless post, it is because both modules use STMicro MCUs, but I think the MAMWLE is a slightly different machine in its intended application. While both are designed for IoT – and the RAKwireless module certainly covers a much larger frequency range for a more flexible network – Move-X’s module is an absolute powerhouse with 66 pins while maintaining a tiny power consumption of 0.255 μA in standby mode.
The MAMWLE embeds a low-power sub-GHz radio for LoRa®, (G)FSK, (G)MSK, and BPSK in the 868-915 MHz band, with up to +22 dBm output power. Two on-board power amplifiers allow for maximum 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 guarantee stability during transmission. With 37 GPIOs, a 15.5 mm x 16.5 mm package, and a huge set of peripherals – I2C, SPI, I2S, LPUART, USART digital interfaces, 12 channels of ADC, a complete set of low-power comparators and timers, and more – the MAMWLE is the perfect device to manage any application board. Thanks to the flexible pinout, all these features can be used simultaneously and multiplexed to optimise PCB routing. Antenna connection is provided through an on-board u-fl coaxial connector, so there is no need to deal with RF signals off-chip, though a 50-ohm pin is provided for your own antenna designs.
Produced in an Arduino MKR form factor, the Cicerone platform is perfect for evaluating Move-X’s MAMWLE device within tracking applications that need meter-level accuracy and long-range, low-power LoRaWAN connectivity. The second heart of this board is the u-blox MAXM10S, a professional-level GNSS device, and the board is also designed to extend the battery life of IoT asset tracking applications thanks to an on-board LiPo charging circuit and u-blox CloudLocate positioning; I think we can now see the different markets that Move-X and RAKwireless are catering to with their technology.
Alternatively, there is an older development kit that allows users to test and program the MAMWLE for their own application. This is more of a breakout board with some useful buttons and test points, so I have included an application form for this option much like I did for the RAKwireless post.
