2. GENERAL PRODUCT DESCRIPTION
Overview
The SE868SY-D module, the latest addition to the xE868 family, is a multi-frequency and
multi-constellation GNSS receiver.
The SE868SY-D product uses the two GNSS bands L1 and L5 to achieve sub-meter
accuracy and reduce the multipath effects that are common in urban canyons.
The SE868SY-D operates at 1.8 V, minimizing power consumption even below L1-only
products and making it ideal for battery powered and wearable device applications.
Product Variants and Supported Satellite Systems
The SE868SY-D is available in two different ordering part numbers:
•
Standard
•
Low-power (requiring an external 0.8 V voltage supply on pin27)
Table 2, below lists the supported satellite systems, for both variants.
