Here are some picture and video of soldered led matrix driver board. All components were placed by hand using fine tip tweezers. It took me around 45 min to setup and 15 min to place all of the components. There were no solder bridges after reflow, only few unsoldered pads(U13 last picture) that needed to be reheated with soldering iron. Next up is writing test code while I wait for stencil for led matrix PCB(It takes long becouse it is free). Soldered led matrix PCB will be shown in "Soldering - Part 2." project log.
