Industrial OA3MRF24J40MB Control Module Segment Coordinator

OA3MRF24J40MB is a Microchip Technology spread-spectrum radio module that provides a 2.4 GHz IEEE 802.15.4 transceiver as a modular radio front-end to be embedded in host equipment. The module carries FCC ID OA3MRF24J40MB and is described in the FCC grant as a single modular spread-spectrum transmitter operating under Part 15 rules, designed for integration into a larger device rather than as a standalone product. In the 2405–2475 MHz band, the grant lists an RF output of 0.111 W, reflecting its regulatory emission characteristics. As part of Microchip's MRF24J40MB family, this module enables wireless networking in embedded systems that require 802.15.4‑based communication, providing a mature, vendor-supported solution for designers building sensor networks or control links.
