If you’re looking for some cheap cables I can recommend you wander down to your local pound shop. I’ve been using their cheap usb cables for a while and they work a treat. They are especially useful if you want to connect up a Wemos or Heltec device to a power supply. They have a good length, 1.5 m, the connectors are sturdily attached, they are packed in a nifty little bag and they only cost one pound each.
I’ve also been using their one pound HDMI cables and they seem to work fine. It seems that electricity doesn’t mind the price of the wires that it travels down…..
