30 Aug 2020 23:42 Package arrived very quickly (less than 2 weeks for France) and very well packed in a stong cardboard box. All works well (I built & tested it before giving feedback) - EXTREMELY PLEASED ! Notes : the power supply is with US plug (should have asked if european plug was possible) - the transducers do need to be polarity tested (about 1/3 wrongly labeled) - Nano needs to be programmed with code from "Instructables" (select board Atmega328P old boot loader) - had 4 extra transducers = very useful for tests with scope as receiver and as spares (once mounted, scope tests showed one of the 72 was not transmitting properly) - power consumption is about 0.7A @ 9V, so hbridge module gets hot (but is OK). |
