Dans mon cas, c'était LE seul appareil simple d'utilisation avec lequel j'ai pu travailler avec la V3 du réseau Things. Plus tard, j'ai acheté une carte TTN UNO d'Arrow, mais c'est beaucoup plus cher et pas aussi facile à utiliser, même si je suis un programmeur C++ expérimenté. Compte tenu des E / S de cet appareil, il devrait fonctionner avec tous les cas d'utilisation auxquels vous pouvez penser. L'unité est très durable et une construction de haute qualité dans l'ensemble. Les instructions de configuration de TTN étaient claires et concises. Comme d'habitude, RobotShop a livré quelque chose que j'utiliserai tous les jours !
In my case, this was THE only easy to use device I could get to work with V3 of the Things network. I later purchased a TTN UNO board from Arrow, but that is considerably more $ and not as easy to use, even though I am an experienced C++ programmer. Given the I/O this device has, it should work with every use case you can think of. The unit is very durable and a high-quality build overall. The instructions for configuring TTN were clear and concise. As usual, RobotShop delivered on something I will use everyday!
