Easy placement of kicad components calculated from reference number. example for SN410501N

kicad_pcb_sort.py

import re

	ref = int(m.group(3)) - 1
	x = ref // 10
	y = ref % 10
	
	x *= 25.25
	y *= 19.25

	return f"{m.group(1)}{x} {y}{m.group(2)}{m.group(3)}"


with open(file, "r+") as f:
	text = f.read()
	text = re.sub(r'(module SN410501N.+\n.+at ).+(\)\n.+\n.+U)(\d+)', place, text)
	f.seek(0)
	f.write(text)
	f.truncate()
