- Wide Temperature Range ( -67F to 257F) ( -55C to 125C )
Blank PCB (top Side)

Blank PCB (backside)

Place and Solder 28-pin IC Socket (U1)

Note:There is a dimple on this device. It should be oriented to the right side of the circuit board.
Place and Solder Slide Switches (S1, S2)

(S1) - Fahrenheit vs Celsius
(S2) - cool vs heat
Place and Solder (R1, R2, R3)

300 ohm resistors [orange, black, brown, gold]
Place and Solder a (R1)

1k ohm resistor [brown/black/red/gold]
Place and Solder Diode (D2)

Note:The black line must be on the right side of the circuit board.
Place and Solder the 16-pin 595 Mux Expander Chip

Note:There is a dimple on both devices that needs to be oriented on the right side of the circuit board.
Place and Solder Decoupling Capactiors (C1, C2)

Note:Orient the minus sign on capacitors to the right side of the circuit board. The long leg must go in the square shapped pin.
Place and Solder (R5)

4,700 ohm resistor [yellow, violet, red, gold]
Place and Solder 2N3904 Transistor. (Q1)

Note:Orient the flat side of the transistor towards the left edge of the circuit board.
Place and Solder 7-segment Display (D1)

Place and Solder Both (CONN3) and (CONN1)

(CONN3) - DC barrel jack
(CONN1) - AC cord receptacle
Place and Solder the Blue Terminal Block (CONN4)

Note:Make sure the open side faces the right edge of the circuit board.
Place and Solder the Large AC Receptacle (CONN2)

Note:This device has 2 solder points on the top side and one on the bottom side of the circuit board.
Place and Solder Large Blue Relay (K1)

Note:The text should appear upside down.
Place and Solder (C1, C2)

Note: Orient the minus sign on the capacitors to the right side of the board.
Place and Solder (U2) and (S3, S4)

(U2) 5v regulator
(S3, S4) Push buttons
Squeeze Your Microcontroller Leads to Fit the IC Socket (U3)

This Is the Amount of Curve You Are Looking for on the Leads.

Install the 28-pin AVR Microcontroller

Note:There is a dimple on this device. It should be oriented to the right side of the circuit board.
Solder Female Header for HC-06 Bluetooth Module or TTL Uart Access.

Connect Temperature Probe to 3-pin Terminal Block.

Note:The wires must be connected in the correct order. The colors are labeled on the PCB.
- top: red (vcc)
- middle: black (gnd)
- bottom: yellow (data)
Flip Circuit Board and Use Plastic Rivets to Attach Plexiglass Base.
