We don't quite know what to call this doohicky - some folks refer to it as a USB Condom but that's specifically for when the data lines on a USB port are disabled so that a device charges without data access. This board is a little more advanced: you can manually switch each of the 4 wires on or off for a variety of uses:
- If you want to have a 'charge only' device, simply switch the D+ and D- lines off
- For power monitoring, you can do high side (disable the V+ line) or low side (disable the GND line)
- For tapping into the USB signal, or monitoring the power voltage, keep all the switches on and probe the labelled pads on either side
With the onboard 4-DIP switch, you can flip to your heart's content. Only thing to note is the C&K SDA04H1SBD switches are technically rated for 5V 100mA so we designed this for low-current-draw microcontroller project board hacking. (You could probably go a bit higher but don't tell anyone!)

Deliveries to post office boxes are not permitted where delivery is by courier. If delivery is by courier and nobody is available at the delivery address to accept delivery when delivery is attempted then the courier may either:
- leave the relevant parcel at the unattended address (the courier will do so if specified in your delivery requirements); or
- re-attempt delivery at a later time or date, in which case we may charge you an additional re-delivery fee.
Note that if a delivery is left unattended at the shipping address and is subsequently stolen then the theft is your responsibility, not ours.
