After a long wait the PCBs are finally home and as I started soldering the IC's sockets I noted a mistake on the very first: the 74HCT238 is DIP 16 and on the board are DIP 20... The IC footprint are pre configured on the EasyEDA but I have the fault of not revising one by one...

Well, life goes on and no way to wait another 6 weeks and spend more US$ 40, so I will make a ugly workaround to solve this.

Thanks for reading.

I suppose there is enough room to make a small adapter PCB that plugs on the wrong footprint.

Good luck !
