Product Highlight

  • Module: 802.11 n
  • RF Band: 2.4 GHz
  • Certified: Yes

The AR4100G-BM2D is a is a small form-factor, single-stream, 802.11n Wi-Fi system-in-package (SIP) solution. Developed to support applications hosted by low-resource MCUs that send infrequent data packets over the network

Typically, these 802.11 applications will place a higher priority on system cost, power consumption, ease of use, and fast wake-up times as compared to high throughput. The AR4100 integrates all Wi-Fi functionality into a low-profile, 8.3 mm x 9.2 mm LGA package that can be easily mounted via low-cost PCB manufacturing flows.
