CC2531 Zigbee Coordinator USB dongle for Raspberry, Linux (zigbee2mqtt, raspbee)

Description

This is TI CC2531 USB dongle pre-programmed with ZNP firmware
(For
zigbee2mqtt) so that Host Processor can communicate with Zigbee Coordinator USB dongle over serial interface(/dev/ttyACMx).
I've tested with zigbee-shepherd, xiaomi-zb2mqtt github examples with this ZNP flashed dongle, and was able to discover/control a few Zigbee devices in Ubuntu and Raspberry Pi 3(Smartenit Metering Smart Plug, Xiaomi windows/door sensor, OSRAM Lightify A19).
Will provide how to setup and turn on/off OSRAM Lightify A19 light bulb in Raspberry Pi.
I haven't tested zigbee end devices extensively but you can find compatible devices that they've already tested in github examples.
(for example xiaomi-zb2mqtt github lists up a few cheap xiaomi zigbee devices)
