Lowan LoRa Module LW-M023-VB Manual V1.
(OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15 B (§15.107 and if applicable §15.107) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating. Furthermore the module should be transmitting and the evaluation should confirm that the module's intentional emissions (15C) are compliant (fundamental / out-of-band). Finally the integrator has to apply the appropriate equipment authorization (e.

4. Reference Design 4.1. Announcements The power supply wiring is as thick as possible. It is suggested that the design can provide 500mA current. Radio frequency interface to the antenna solder part line as short as possible, to 50 Ω impedance matching, walk around the line played more holes. The module reset pin suggests that the external environment may cause the module reset by connecting the MCU for control. SPI port and DIO port can add pull resistor as needed.
