Description
Summary
The NM-usb-chain is a NMMiner Offical development board. At first glance, you may think it’s just an ordinary ammeter, but in fact it’s also a lottery ticket. It can not only provice the precise current measurement, but also achieve the same high Hashrate 117KH/s as other ESP32-S3 devices. Most importantly, the nm-usb-chain includes a male USB-A port and a female USB-A port. Multiple usb-chains can be connected in series to form a lottery chain, which is really interesting. Of course, this is not all of the nm-usb-chain functions. With the usb-chain device, you can do that:
-
Daily work and life current monitoring.
-
Lottery when charging your phone.
-
Double your lottery device hashrate without any power supply device added. Such as usb-chain + T190, usb-chain + LILYGO T Dongle S3, etc.
Product Highlights
