Here is the final parts list for the IoTBox. Each item links to the version that I used. They may link to multipacks (I built 30-35 IoTBoxes) but you only need 1 unless noted.
During the beta testing I have tried and killed many boxes and components to get this far. Hopefully it will save you some time and expense. Note that many items came via China to reduce the unit price.
Parts List
- Oled screen – Yellow/Blue I2C protocol
- ESP8266-esp12 version
- ESP8266 adapter board (get this type as it fits nicely in the box. Other suppliers sell the same version)
- DS18B20 Waterproof temperature sensor
- 5v to 3.3v converter (many options available – others may be better but watch out for pinouts changing)
- Plastic Enclosure, 52 x 50 x 35mm (get the Spelsberg Mfr. Part No.13045501, it works nicely with the adapter)
- 5MM RGB Common Cathode LED
- 3 x 100ohm resistors
- Push Button SPST
- Adafruit Micro usb-B breakout board
- Grommet for Temperature lead
- Rubber feet x 4
