I built this drafting triangle to improve my routing skills as well using the render feature , which I hadn't used yet also this scale has Wi-Fi and an inbuilt accelerometer which would allow the user to level
- WiFi and Bluetooth
- Inch and MM scale
- Accelerometer
- RGB LEDs
- User-Assigned GPIO Switches
First connect this device via usb-c cable to your pc then download MicroPython from https://micropython.org/download/RPI_PICO/ then download the python firmware file in Firmware then put it in the root of the pico folder that will appear if Micropython is successfull , Then the led will blink
*Note the firmware is untested
