EBV Electronic and Weptech Elektronk worked closely with STMicroelectronics for the development of a sub-GHz RF module for flexible systems M-BUS and wireless WHO metering. Maya, the newborn in the program of EBVchip, is ideal for metering applications differerenti, including AMR (automatic meter reading), AMI (advanced metering infrastructure), gas meters, water and electricity, as well as devices for reading the heat.
The RF module, factor in compact 11x14mm ideal for SMT assembly, host microcontroller STM32L0 ultra-low-power, low-power transceivers SPIRIT1 the sub-GHz balun Hand-SPI-01D3.
