Electronics
Following are some notes about ST application notes I read to design an STM32L151 board.
I finaly published them: sources of my wireless sensors are available here.
I wanted to try if a 100% DIY process to reflow a small batch of boards. For about 10 boards it is cheaper to hand solder them than ordering a stencil, but I was wondering if it can be faster to manually cut a stencil and reflow the boards on a frying pan.
