Brand: ZigBee and Bluetooth Low Energy wireless radio modules MGM22OP22A and BGM22OP22A and BGX22OP22A Silicon Labs As the manufacturers of the above-listed modules we declare that they are electrically and mechanically identical, and the only differences between models are described in the last row of the table below: Product Zigbee and Bluetooth Low Energy Bluetooth Low Energy wireless radio wireless radio modules modules Model MGM22OP22A BGM22QP22A and BGX22OP22A Spec. Low-Power, Zigbee and/or BLE Low-Power, BLE Antenna Type On board ceramic chip antenna with 1 .86dBi of gain Hardware-wise the modules are identical. These are fully internally regulated and Hardware shielded PCB modules with a single integral ceramic chip antenna. There are no separate variants with an RF pin or a connector for using external antennas. RF max TX power 8.2 dBm Model differences The only difference between these modules concerns the factory software configuration defining which wireless protocol are allowed: - The MGM22OP22A can run Zigbee and/or BLE and/or a simple proprietary protocol as a SRD (Short Range Device) - The BGM22OP22A can run BLE and/or a simple proprietary protocol as a SRD - The BGX22OP22A is identical to the 3GM220P22A, but with another name for marketing differentiation Should there be any query regarding this declaration, please do not hesitate to contact the undersigned.
