Mini USB to UART Stick

Features:Super thin and low-profile PCBNo soldered on USB connector which tends to bend over time from use, causing it to weaken and possibly break off if made from cheap metaldual NPN transistors for programming standalone ESP boards (IO0 and EN)broken out lesser-used CP2102 pins which are used in more complex chips and progamming methodsPCB orderingSet thickness of the PCB to 2-2.4mm. a 1.6mm PCB would not fit well in a USB-A port, causing it to fall out.Order the PCB with the ENIG finish if possible. HASL is fine, but may not be as long-termI ordered the black soldermask, but color is optional.If you are in the UK, give PCB Train a shot, and see if their services work for you. PCB Train offer an assembly service too, but I suggest assembling it by hand if possible to save cost.Bill of Materials1x CP2102 Usb to UART converter (QFN-
