4.4. Software and system Information Operation System Driver Linux 2.4/2.6 Available Android 4.1 Available Windows XP/Vista/7/8 Available Mac OS X 10.3~10.8 Available 5. Agency Approval CAUTION: This module must be installed and operated in accordance with provided instructions and the antenna used for this transmitter must be installed to provied a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
7.1. Power supply: 1) The input power can be 5.0VDC or 3.3VDC, please mentioned it when place an order. 2) The operation current of 5.0VDC power input will be different with that of 3.3V power input. The external power shall be well designed with enough capacity. 3) Should 3.3VDC power be selected, please be sure it’s clean with low ripple; otherwise, the EMI or RF performance might be deteriorated. 7.2.
7.5. Soldering requirement: The module is not recommended using reflow oven process, hand soldering is suggested. If reflow oven process is selected, please keep good control on the soldering process. Otherwise the flow air might blow components removing. A reference flow chaw likes as following: Information in this document is subject to change without prior notice.
Notes: user should adjust setting of reflow oven to get best soldering quality 8.
