+
+
+
+* Delete junk kicad and model files.
+
+
+
+
+----- Done
+
+* Verify drill size of Molex pins
+
+* Add a way to configure current range. E.g. via resistor.
+
+* Increase horizontal clerance for the four screws. (extend the PCB).
+
+* Reduce diameter of vias in ground pads of the pico
+
+* Update instruction silk messages on the PCB (e.g. tape thickness)
+
+* Verify sufficient clearance at the sides of the TFT, for buttons and LEDs.
+
+* Make the LED footprint compatible with 0603 and 0805 LEDs.
+
+* Clearer mark for pin 1 of the current sensors. E.g. a dot.
+
+* Change the order of FPC 6 pins, to match the flat cable
+
+* Add F-Silk marks with the stepper connector pin lables (A1, A2, ...)
+
+* Move the Molex connector to be at 50 mill relative pitch
+
+* Finalize BOM.
+
+* Finalize the choice of connectors
+
+* Smaller holes for the MOLEX connectors?
+
+* MOSFET footprint too small?
+
+* Smaller holes for the ground pads of the Pico?
+
+* Move the BOOTSEL pad closer to the Pico's switch.
+
+* Remove SWD pads from the PCB
+
+* Diode footprint too small ?
+
+* Lower profile switches
+
+* Move the Molex connectors slightly out?
+
+* Move LED 1,2 test points to the front of the board.
+
+* Add duplicate leds on the front of the board.
+
+* Review through holes
+
+* Add a silkscreen text below the Pico to place Kapton tape here.
+
+* Is the pullup resistor of the BOOT switch required?  
+
+* Add mechanical dimensions.
+
+* Add duplicate BOOT, RESET button on the front side (?)
+
+* Add silkscreen marking for TFT position.
+
+* Change the Pico pin silkscreen labels to reflect the function of the pin in the analyzer design.
