The EVA2135-H demo board offers the possibility to implement the A2135-H GPS
receiver module temporarily into your design by using the terminal block with 15
connections & a pad of 3V3. To operate the EVA2135-H via this terminal block,
please check “Table 3: Switch settings”.
Please note:
•
VCC power input is
not
