3b32 module is a low-power zigbee rf module based on efr32 chip of silicon labs company. it can be widely used in the field of short-distance wireless communication networking, with low power consumption, small size, strong anti-interference ability and other characteristics. the module uses special high dielectric constant and low loss board for rf, and uses four layer board for wiring.

  • transmit power: 19.5dbm
  • support agreement: zigbee3.0
  • communication distance: 300m
  • core programme: efr32
  • core strengths: long distance mesh

3b32-v102 module is based on efr32mg1b232f256gm32-c0 of silicon labs. the efr32mg1b232f256gm32-c0 is a true system-on-chip (soc) solution for zigbee, thread and multiprotocol, and it supports the following modulation formats: 2/4 (g)fsk with fully configurable shaping, bpsk / dbpsk tx, ook / ask, shaped oqpsk / (g)msk, configurable dsss and fec. the module enables industry-leading energy efficiency, ultra-fast wakeup times, a scalable power amplifier and no-compromise mcu. it integrates 32-bit arm ò cortexò-m4 core with 40 mhz maximum operating frequency, pa with up to 19.5 dbm and balun. 

 

 

• 40mhz 32-bit arm cortex-m4f core mcu with up to 1mb flash memory, up to 256kb ram • rf frequency range: 2.4ghz ism band

• rf output power: up to 19.5dbm

• integrated dc-dc converter with rf noise mitigation

• 12-channel peripheral reflex system enabling autonomous interaction of mcu peripherals

• hardware crypto accelerator and true random number generator

• protocol stack: zigbee, thread, zigbee rc. also bluetooth smart and proprietary on performance parts
