Start by arranging all of the parts of the kit as shown. Make sure you have all of the parts listed.
Note: Some parts in the bill of materials come pre-installed on the PCB, as shown.
- (1) Rescue Shield PCB with DC-DC step up converter pre-assembled, as shown
- (1) 1×36 pin breakaway male header
- (1) 28 pin socket
- (1) 20 pin socket
- (1) microswitch pushbutton
- (1) 3mm red LED
- (1) 3mm green LED
- (2) 1k resistors (brown-black-red-gold)
- (1) 330 Ohm resistor (orange-orange-brown-gold)
- (18) 100 Ohm resistors (brown-black-brown-gold)
Examine the PCB. The PCB should have some parts already soldered near the lower left corner – this is the surface mount DC-DC converter.
Install the two IC sockets, marked IC1 and IC2. The notch in one end of each socket should be oriented such that it matches the notch shown in the PCB silkscreen.
Install the pushbutton, S1, and resistors R19, R20, and R23. Resistor R19 is 330 ohms (marked orange-orange-brown-gold). Resistors R20 and R23 are 1k (marked brown-black-red-gold).
Install resistors R1 through R19. All of these resistors are 100 Ohms (marked brown-black-brown-gold).
Install the LEDs. LED1 is the red BURN LED while LED2 is the green READY LED.
The LEDs have two leads. One is longer, this is the positive lead. Install the LED so the long lead goes into the hole on the left, near the small + symbol.
Break the 0.1″ header into two sections of 6 pins and two sections of 8 pins. Install the header strips into the board from the bottom side, so the shorter pins stick up through the board, as shown. Make sure the headers sit roughly 90 degrees from the PCB so that they point straight down. I find it helpful to solder one or two pins and check the alignment of each header before soldering the rest of the pins.

That’s it, you’re done!
