  • It is possible but very difficult unless you’re good at soldering fine pitch SMD parts. (The pins on this module are very small and close together.) We have the same module on a breakout board that might be easier for you to use.

  • We don’t have plans for a Si4777 breakout board unfortunately. Even if we did, the licensing costs associated with HD radio would probably make a breakout cost somewhere north of $100. Until the company that owns the patents on HD radio releases details on how to decode their CODEC without paying a fee, you’re never going to see a HD radio receiver in the hobby electronics world.

  • You can power the board from USB through the USB socket. The 7-15 volt limitation is only if you use the barrel jack that’s to the right of the USB socket.

  • Not sure about the one in the picture, but the build list for this board has a 220 ohm resistor in it and no 1.2K resistors. Rest assured the product we actually ship has a 220 ohm resistor.

  • My mistake, I was looking at the other tags that peel off the white backing. For this tag, just cut between them leaving the foil antenna sections untouched and you should be OK.

  • The entire foil section of these peel away from the white backing. You don’t need to cut them, but can if you want to. Just don’t cut anything metal.

  • Yes, these can withstand being submerged. In fact, you can read them while submerged, but the read range will decrease. I just tested one inside a glass of water and it reads just fine! It might be best to cover them in tape just to be sure though. I don’t know how long they can withstand being under water.

  • analog input lines do not work properly when this shield is in place.

    This shield uses all six of the Arduino’s analog pins for shield functions already. If you don’t need wind direction and modify the code, you could free up A0 for your own use.

    GPIO pins on the Pimoroni Explorer HAT Pro work differently than on an Arduino

    GPIO outputs on the Pimoroni Explorer HAT Pro go to ground when active so if you’re connecting a LED or other device to them, connect the positive leg of your device to +5 or +3.3 volts and the negative end to whichever output you choose. When that output is active, it gets connected to ground, completing a circuit.

  • Sounds like you have a baud rate mismatch. Double check to see you have the Serial Monitor set to 115200 baud and see if that clears things up for you.
