Step 3:
Now, insert and solder U1’s 20-pin socket. A
handy tip is to place a piece of Scotch tape over
the socket once it has been inserted into the PCB
to prevent it from falling out when you flip the
board over to solder. This part is the trickiest for
beginners, as the pins are spaced close together,
so be careful not to create any “solder bridges”
between pins.
Once the socket is soldered into place, remove
the tape if you used any and align U1 so the
notch on its plastic packaging is facing to the left
(so pin 1 is at the lower-left corner of the socket).
Gently but firmly press U1 into the socket,
ensuring that all the pins are seated properly
within the socket and none of the leads have
accidentally bent outwards.
Step 4:
Finally, flip the circuit board over and solder the
BT1 battery holder, the only surface mount part in
the kit, onto the backside of the board. Pay close
attention to the positive (“+”) and negative (“-”)
markings on the plastic part of the holder and
align the positive side with the “+” marking on
the circuit board.
Step 5:
With the kit assembly complete, the last step is to insert the CR2032 Lithium coin cell battery into the
holder. Slide the edge of the battery towards the “+” side of the battery holder and underneath the two
gold “teeth.” Then, press firmly down on the other edge of the battery until it snaps into place within the
holder.
