this line is used to control the transmission mode of the RS-485 transceiver

Contains an SHT-30 Temperature/Humidity sensor

it can't configure the LS20031 GPS receiver module

We gave the M0 pads the exact same names as the original Trinket so all your existing Arduino code will work exactly the same as-is without changes

Addressable High-Density RGB 144-LED Strip, 5V, 1m (SK9822) ARM this line is used toThis high density LED strip has a length of 1 m and contains 144 RGB LEDs that can be individually addressed using an easy to control SPI interface, allowing you full control over the color of each RGB LED. The flexible, waterproof strip runs on 5 V and can be chained with additional SK9822 strips to form longer runs or cut apart between each LED for shorter sections.
