GTOP LadyBird 1(PA6H) GPS Module
20 or more $16.00
Unlike any PA6 series in 16 x 16 x 6 mm size, LadyBird-1 has a lower overall profile of just 4.7mm. This makes it easier for LadyBird-1 to be more readily incorporated into any circuit board design for small form-factor devices. Although the patch size is thin, its performance stays in the excellent quality of PA6 family. It supports up to 66 channels of satellites searching under -165dBm sensitivity, plus 10Hz maximum update rate for precise GPS signal processing under low receptive conditions. LadyBird-1 is a low consumption GPS module (20mA at tracking and 25mA at acquisition).
LadyBird 1 (PA6H) module built-in 15x15x2.5mm ceramic patch antenna on the top of module, that achieves the industry’s highest level of sensitivity (-165dBm ) and instant Time-to-First Fix (TTFF) with lowest power consumption in a small form factor (16*16*4.7mm).
