Ligne 7 :
Ligne 7 : − The Pico is the MicroControler propeling the board.+ − It is soldered on the top of the Cansat Base Board, this can be done with Pin Header or directly flat on the board.+ − − − − Lets starts to assemble it! − + − + − − If you are more confortable with leveled board to work on then place the piece of cardboard under the board to help you when soldering. − − {{asm-row|img=ENG-CANSAT-PICO-11.jpg}} − {{asm-text}} Cut two sections of pins, we will is them to align the Pico to solder it. − − {{underline|Tip:}} Make a section of 8 pins, it can be reused to solder the powerboost. − − Place the long part of the PinHeader in the Pico holes (from under board) as shown on the picture. − + − + − + − + − Place the bit of iron just at the separation between the two boards.+ + − Melt solder... it will start to melt on the base board then also wet the Pico pad.+ + + − Voilà! you just learn to solder a castelate pad. Repeat the same operation on the opposite side to secure the Pico on the base.+ + − {{asm-row|img=ENG-CANSAT-PICO-14.jpg}} − {{asm-text}} Remove the pin headers then solder the remaining pads.

{{asm-text}} Pick up the base board and place it with the top part up. You should see the message "Raspberry Pico (This side)" on the board.
{{asm-text}}Take the base board and orient the board to see the '''USB''' label on the left and the "Pico/MCU facin this side" in front of you.

{{asm-text}} Place the Pico on the top of the board. It should be perfectly aligned thanks to the pin header.
{{asm-text}} Grab the CPU board with the microcontroler facing front.

{{asm-row|img=ENG-CANSAT-V2-ASSEMBLY-12.jpg}}
{{asm-text}} Solder two opposite pads on the board to make the Pico staying on the right place.
{{asm-text}} Now, insert the MCU board onto the 2x20 pin connector.

{{asm-text}} Even when not required yet, user can pick the Lipo battery then plug it into the 2 poles JST connector (facing the microcontroler).
{{ambox | text = As soon as the battery is connected it will start to discharge in the board. The discharge can be compensated:
* either by plug in power on the USB connector.
* either by shorting the pads of "PWR Enable" connector (MCU sill also shutdown).}}

{{asm-text}} When required, plug the µFl antenna coax.
