SAD HAPPY To discover that the elusive bit that you want is stocked in the Silicon Chip ONLINE SHOP! There's a great range of semis, other active and passive components, BIG LEDs, PCBs, SMDs, cases, panels, programmed micros AND MUCH MORE that you may find hard to get elsewhere! Because you can't find that difficult-to-get special project part at your normal parts supplier. . . Or perhaps they've discontinued the kit you really want to build. . . If it's been published in a recent Silicon Chip project and your normal supplier doesn't stock it, chances are the SILICON CHIP ONLINE SHOP does! HERE ARE JUST SOME EXAMPLES (oodles more on our website!) WeMos R1 D2 WiFi Board A WeMos R1 D2 Arduino-compatible WiFi board which includes a connector for an external antenna.
