The NB-MMC44x series ZigBee wireless transmission modules are based on Silicon Labs’ advanced low-power wireless connectivity chip EFR32MG13P, with small size and low power consumption. The NB- MMC44x modules support ZigBee 3.0，BLE, BLE-Mesh, Thread, and other protocols.
The enhanced CPU architecture is a single instruction cycle, and the peripherals are very rich, serial port, PWM, analog-to-digital conversion, timer, and power control have been integrated. The industrial-grade chip can work in very harsh environments.
The NB-MMC44x modules have all IO ports reserved for unrestricted use. The modules have a wide range of potential applications because of their transmission and anti-interference capability.
The NB-MMC44x series modules consist of main chip, clock circuit, RF circuit, reset circuit, interface circuit, onboard antenna, and u.FL antenna terminal. Cortex-M4 CPU, frequency clock 40MHz, 256-1024KB flash, 32-256KB RAM, 29GPIOs.
The NB-MMC44x series modules are available in two packages, 20PIN (21mm*16mm) and 36PIN (25mm*16mm).
