Bonjour Yann, Bienvenue à EasyEDA. Your schematic is a little hard to read so it is not so easy to check that it is correct to the original. If you can redraw it a little more clearly then it will be easier to verify. Also, if you can you post a link to a public copy of your schematic rather than just to an image then viewers can user the EasyEDA Design Manager (the tab at the top of theright hand panel) to check the design properly. https://easyeda.com/Doc/Tutorial/share.htm#Sharing :) There are some good guidelines for drawing circuit diagrams here: http://michaelhleonard.com/how-to-design-the-perfect-pcb-part2/ and a little more in my later post here: https://easyeda.com/forum/topic/PCB_not_what_is_on_the_drawing-KB71jdvN5 and for when you want to finish the PCB design: https://easyeda.com/forum/topic/The_best_way_to_design_a_PCB_in_EasyEDA-ThR3pwqIC https://easyeda.com/forum/topic/Essential_checks_before_placing_a_PCB_order-UuohztL3l (If you want to simulate this design to check that it is wired up correctly and does what you want, see: https://easyeda.com/forum/topic/How_to_find_simulatable_parts_in_EasyEDA-1YgasK2kC)

Ok, thank you :) I'll see what I can do
