Order recommendation:
- Start with SMD components (FET, EEPROM, resistors)
- ...
- Switches
- 40-pin Header
- 8-pin Header (need soldering before Buzzer!)
- Buzzer
- 14-pin socket 100nF capacitor backside
- 14-pin Socket
- Place electrical tape on backside of 7-seg display
- 7-seg display
Hints:
- Swiches: Only solder two opposite contacts
- Standing resistors: Solder short wire first
- Solder R8, R9, R10 lying on backside (to not disturb switches) or
- Advanced people can solder SMD1206 resistors instead of classic standing ones
- Buzzer can be very loud, solder 47 KOhm resistor for silent operation
- Solder DS18B20 with maximum wire length to keep it away from board heat sources

1 x DS18B20 (IC1)
1 x TM1637 4 Digi LED display modul (GND, VCC, DIO, CLK)
1 x Buzzer (O 12mm, 7.2mm holes) (SG3)
1 x FET IRLML6401 (Q1)
1 x EEPROM STM M24C64-WMN6 (24C64) **
2 x SMD 1206 resistor 3K9 (R18, R19)

* Please choose LED resistor corresponding to LED type and 3.3 V, usually 1 KOhm is ok, but our green LED is a low current type, so even 47K makes a satisfying light
** Different sizes and manufacturers are possible if EEPROM comply with the Raspberry Pi HAT EEPROM specification (8 bit data, 16 bit address, I2C @ 100 kHz, 3.3 V)
