-It's working out around €16 per PCB for 5 PCB's and all the parts, then a minimum of €5 to land a Pico 2040 outside the UK, the costs are around €21, if you can buy a populated board for less, it's probably worth voiding the hassle of parts, soldering etc. So a populated programmed board will have to sell for €42 plus shipping costs.

+Before inserting the microcontroller and drivers into the board, fist set the step down regulator to 5.1V, failing to do so will fry the Pico board.

+The DIP switches on the board nex to the stepper is wired to VIO, so to set Micro-stepping simply turn them on or off using this table.
