It is recommended to weld the board in the following order:

1 PCB PCB All the components must be welded in the back side of the PCB, except the 2x20 pins connector.
2 2x20 pins connector 2x40 pins connector The 2x20 pins connector must be welded in the front side of the PCB. 
3 Connectors adc connectors
  • 2x1 Pins red  --> "WP"
  • 2x1 Pins red --> "BACK PWR"
  • 2x1 Pins black --> "EEPROM"
  • 3x1 Pins black --> "CE0/CE1"
  • 4x2 Pins black --> "VREF_SEL"
  • 8x1 Pins black --> "0-7"
  • 8x2 Pins black --> "POWER OUT"
4 IC Sockets ADC Sockets

The rounded edge must be toward the square hole in the PCB

  • DIP16 (8x2 Pins) --> "MCP3208"
  • DIP8 (4x2 Pins) --> "AT24C64"
5 2 pins polarized connector 2 pins polarized connector
  • 2x1 Pins white --> "5V INPUT"
6 8 pins array resistor B type 8 pins array resistor
  • 2 x SIL8 (8x1 Pins) --> "A1" and "A2"
7 Resistors ADC Resistors
  • 1 x 1K (brown, black, black, brown, brown)
  • 2 x 3K (orange, black, black, brown, brown)
  • 2 x 3.9K (orange, white, black, brown, brown)
  • 1 x 10K (brown, black, black, red, brown)
  • 1 x 12K (brown, red, black, red, brown)
  • 2 x 47K (yellow, purple, black, red, brown)
8 Capacitors ADC Capacitors
  • 2 x 0.1uF capacitors --> "0.1uF"
9 Transistors ADC Transistors

For 2N7000 and 2SJ378 the pins No. 1 are at left, when you are reading the letters on transistors. For 2N2907 the pins No. 1 are at right, when you are reading the letters on transistors. Pin No. 1 must match the square hole in the PCB.

  • 2N7000 --> "Q1"
  • 2N7000 --> "Q2"
  • 2N7000 --> "Q3"
  • 2N7000 --> "Q4"
  • 2N2907 --> "Q5"
  • 2N2907 --> "Q6"
  • 2SJ378 --> "Q7"
10 Chips ADC Chips

Insert carefully the chips into the sockets, the pin No. 1 of the chip must be toward the rounded edge of the socket.

  • Microchip MCP3208
  • Atmel AT24C64
11 Jumpers ADC Jumpers

Insert the jumper's caps

  • Red (default OPEN) --> "WP" 
  • Black (default SHORT)--> "EEPROM"
  • Black (default CE0) --> "CE0/CE1"
  • Red (default SHORT) --> "BACK PWR"
  • Black (default 5V) --> "VREF_SEL"
