Good product that comes into pre-cut board (especially if you order more than 1x 5), has to be separate by hand, but it is not a problem. Tiny board that fit perfectly my project. Very simple, Tx in ;Rx in ; Tx out ; Rx out ; – (GND) and (3.3V or 5V). Tested and works good. Well packed – Box & bubble bag. Quick delivery in the actual international Covid context, within 15 day by DHL 6-10 days.
