8. Layout suggestion 8.1 Power supply precautions • Module power: 3v button battery or DC 3.3v • Connect the power pin capacitors as close as possible to the chip and pins • Use capacitors to decouple power from the chip • Use capacitors to prevent noise from coupling back into the power plane Note: When supplying power to the module, it is necessary to use a small ripple (generally, the power ripple within 30mV is sufficient).
Note: Pin19 Need to be grounded. 8.
9. Packaging and Labeling Each reel or tray will be placed in an antistatic bag with a desiccant bag and a humidity card, and in a 36x25x12cm box. Antistatic warnings and labels are attached to the outside of the packaging. 9.
