@tobias-h said in UHF RFID Unit (JRD-4035) on Arduino Uno: E.g. what board to select in the board manager ? In the Arduino IDE select: Tools - Board - Arduino AVR Boards - Arduino Uno. May I suggest you first get more familiar with the Arduino IDE, your Arduino Uno board and some simpler sketch examples for the Arduino Uno? Then maybe do some experiments with the serial connection (which is needed to talk to the UHF RFID Unit)? Alternatively you can always get an M5Stack device for which the example has been written. Thanks Felix

@ajb2k3 在 Project Element E 中说： Brushless drivers are ok for the Brushless motors but the same board needs to replace a burned out driver in an old bike. The old bike has a 200W motor run at 36v for a total of 5.55555) amps and the FQA160's are rated at 160amps. However, I must say that those ESC's do look sweet. In this case, consider something like this: [image: gs30-esc.jpg] Is way cheaper.

@calin Sweet, thanks for taking the time to answer my questions.
