Firmware Update/Flashing
Firmware Update/Flashing in Nixie Clock Shield NSC314
Step 1: Power your clock using a 12-volt 1-ampere power supply.
Step 2: Connect your clock to your PC using a USB cable. Depending on the clock model, you may need either a USB-A to USB-B cable or a USB-A to micro-USB cable.
