We started pcb development and we want to keep low cost (2 layers) and ease of assembly.
So we spoke once again with Microchip marketing and we decided to use 44pins QFP instead of Qfn. Yes 4mm bigger but easier to solder (0.8mm pitch)
We also decided to avoid smt side pads to remain on the 2 layers.
I’ll post the first review of PicusWiFi PCB tomorrow and in 10 days we’ll assemble 10 samples to start apps development
