Unit GPS

SKU:U032

Description

Unit GPS is a satellite positioning Unit. It integrates the AT6558 BeiDou navigation chip and the MAX2659 signal amplification chip, providing high-quality satellite positioning services.

AT6558 is a high-performance navigation chip that supports multiple satellite navigation systems. It can receive satellite signals from 56 channels and simultaneously receive GNSS signals from 6 satellite navigation systems, achieving combined positioning, navigation, and timing to obtain accurate global location information. The AT6558 can quickly and accurately locate in areas with weak signals such as cities, canyons, under elevated roads, and anywhere inside a vehicle. This module can be widely used in products like vehicle monitoring, bus stop announcements, vehicle navigation, ship navigation, and laptop navigation.

When using, please connect this Unit to PORT C, it will communicate with M5Core via the UART protocol.

UART parameter settings:

Baud rate (default: 9600bps)
Start bit (1 bit)
Stop bit (1 bit)
Parity bit (none)
