Here‘s a good, balanced review from SmittyTone of the Pibrella from Pimoroni/Cyntech. He’s gone into some depth here, particularly reviewing the software library that comes with it. Not sure I agree with the criticism that it looks like a toy – it’s supposed to appeal to kids, after all. But, as I said, it is a well-balanced review that is 95% positive. Read it here. You can buy the Pibrella from The Pi Hut, Pimoroni or Cyntech (or several other sellers)
