**Requirements**
|
|
|
|
- Microcontroller programmable in MicroPython
|
|
|
|
- Ethernet
|
|
|
|
- USB connection
|
|
|
|
- optional screen
|
|
|
|
- cheap enough (so we can have a collection of spares)
|
|
|
|
|
|
|
|
**Base system**
|
|
|
|
- Raspberry Pi Pico (W)
|
|
|
|
- Wiznet W5500 Ethernet adapter
|
|
|
|
- Waveshare PICO LCD 1.3
|
|
|
|
- ? USB adapter
|
|
|
|
- 24LC32AT EEPROM
|
|
|
|
|
|
|
|
**Sensors**
|
|
|
|
- SHT25 relative humidity and temperature sensor
|
|
|
|
- LPS28DFW pressure sensor
|
|
|
|
|
|
|
|
**Rejected hardware**
|
|
|
|
- Waveshare 2-CH UART TO ETH
|
|
|
|
- requires two UART channel for I/O – no more UARTS left on the Raspberry Pi Pico
|
|
|
|
- no driver for the Python standard network library |
