When batteries are present, the main
switch operates as Wakeup-Standby.
Without batteries, it acts as On-Off.
J12 provides an easy way to
access the VADC and 3V3
supplies but should not
be jumpered.
Connectors J4, J5 and J6 are shown as oriented in the evaluation kit.
Note: GPIO2_A/B & GPIO3_A/B are selected
from J10A (left module connector) and J10B
(right module connector) via switch on GPS2058
module adaptor card; switch-down selects
GPIOx_A and switch-up selects GPIOx_B
