Introduction: YATC5 - Temperature Controller Assembly Instructions
The YATC5 is designed to make the fermentation of foods as easy as possible. Version 5 has many unique features. It is available for sale in kit or assembled form.
- Waterproof - 3' long temperature probe
- Datalogging - drop in bluetooth module or TTL serial
- 100% Open Hardware
- Digital Display
- Celsius or Fahrenheit configuration
- Memory - save settings through blackouts
- Wide Temperature Range ( -67F to 257F) ( -55C to 125C )
Step 1: Blank PCB (top Side)
Step 2: Blank PCB (backside)
Step 3: 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.
Step 4: Place and Solder Slide Switches (S1, S2)
(S1) - Fahrenheit vs Celsius
(S2) - cool vs heat
Step 5: Place and Solder (R1, R2, R3)
300 ohm resistors [orange, black, brown, gold]
Step 6: Place and Solder a (R1)
1k ohm resistor [brown/black/red/gold]
Step 7: Place and Solder Diode (D2)
Note:The black line must be on the right side of the circuit board.
Step 8: 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.
Step 9: 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.
Step 10: Place and Solder (R5)
4,700 ohm resistor [yellow, violet, red, gold]
Step 11: Place and Solder 2N3904 Transistor. (Q1)
Note:Orient the flat side of the transistor towards the left edge of the circuit board.
Step 12: Place and Solder 7-segment Display (D1)
Step 13: Place and Solder Both (CONN3) and (CONN1)
(CONN3) - DC barrel jack
(CONN1) - AC cord receptacle
Step 14: Place and Solder the Blue Terminal Block (CONN4)
Note:Make sure the open side faces the right edge of the circuit board.
Step 15: 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.
Step 16: Place and Solder Large Blue Relay (K1)
Note:The text should appear upside down.
Step 17: Place and Solder (C1, C2)
Note: Orient the minus sign on the capacitors to the right side of the board.
Step 18: Place and Solder (U2) and (S3, S4)
(U2) 5v regulator
(S3, S4) Push buttons
Step 19: Squeeze Your Microcontroller Leads to Fit the IC Socket (U3)
Step 20: This Is the Amount of Curve You Are Looking for on the Leads.
Step 21: 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.
Step 22: Solder Female Header for HC-06 Bluetooth Module or TTL Uart Access.
Step 23: 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)
