Figure 5. The SMT
footprint of the Pico W
Rev3 board.
The footprint shows the test point locations and pad sizes as well as the 4 USB connector shell ground pads (A,B,C,D).
The USB connector on Pico W is a through-hole part, which provides it with mechanical strength. The USB socket pins
do not protrude all the way through the board, however solder does pool at these pads during manufacture and can stop
the module sitting completely flat. Hence we provide pads on the SMT module footprint to allow this solder to reflow in
a controlled manner when Pico W goes through reflow again.
For test points that are not used, it is acceptable to void any copper under these (with suitable clearance) on the carrier
board.
2.3. Recommended operating conditions
Operating conditions for the Pico W are largely a function of the operating conditions specified by its components.
Operating Temp Max 70°C (including self-heating)
Operating Temp Min -20°C
VBUS 5V ± 10%.
VSYS Min 1.8V
VSYS Max 5.5V
Note that VBUS and VSYS current will depend on use-case, some examples are given in the next section.
Recommended maximum ambient temperature of operation is 70°C.
