SMT Kit Documentation

 

IMPORTANT: For those that have purchased a kit. The silkscreen indication on the PCB for the orientation of D3, D4 and D5 are backwards. These parts need to be installed “Backwards” on the circuit board for the board to function.

ADDITIONAL: M2 and M4 (BSS138 N Channel FETs) are also in error. Pins 1 and 2 are swapped on the decal from the real part. The easiest fix for this is to install the parts onto the PCB upside down, and fold the legs down to meet the circuit board. M2 is used on the SPI port expander to give one IO with more current ability such as when driving a display back light. M4 is used to enable the 12V boost convertors output to the OLED display connectors. Sorry about that.

  1. Hi Richard!
    Finally got around to finishing my board today. Works great!

    One last thing I noticed is that J14 and J3 in your BOM are swapped (if one wishes to retain compatibility with arduino shields.)

    Thanks! I now look forward to my future SMT soldering tasks!!

    Will
