Note: the part number “CX870-3D” does not use the new numbering scheme indicating
the number of external antenna sockets installed and connected.
* Has two UFL connectors; only CON2 is connected internally. Use CON2 for external
antenna connection.
% The CX870-3DS is the same as CX870-3D, except that the RF shield is soldered in
place.

Timing
The following paragraph in the CX series datasheet in Section 9.1 does NOT apply:
About 1.9V, the arrival of 1.9V supply should lag behind the arrival of the 3.3V. The delay between the 1.9V
and the 3.3V is not critical. Typical delay is approximately 10ms, for example using 10kohm resistor and
0.1uF capacitor on the enable pin of a 1.9V dc-to-dc converter.
This is because the 1.9V supply is included in the module.
