6. Headers (P2): Your kit includes a single row of 14 male headers. These will be installed across
three different locations on the PCB.
First, we’ll install the In-System Programmer (ISP) headers. This is a 2x3 header array that
enables you to plug a cable into your Altura and upload (or “flash”) new software onto the
microcontroller. This is covered in detail in the Altura Reference Manual.
a. Carefully break two pieces of three pins each from the row of headers (24). Place each of
them in the P2 position on the PCB. The short pins go through the board; the long pins point
up. Make sure the bottom of the headers are flush to the circuit board (25). Tack one pin on
each row down with solder while you hold the header in from the top (26). Once each row
has been tacked on, you can solder the other pins in place (27). Remember to properly re-
solder the “tacked on” pins.
