It's a very tight space with a full 40pin chip(52mm) and a 26pin IDC(41mm) on the ECB board (b=100mm). | + | |\\ \\ R04 version:\\ \\ A small adjustment of 1.2mm is needed to get the ECB connector in line with hole\\ \\ \\ Tip: When using a IDC connector, I had to cut the corner of the plastic frame for the 26pin connector or it conflicts with the PIO chip it self (The chip is slightly longer than its socket).
