The RN2483 LoRa® Mote is a LoRaWAN™ Class A end-device based on the RN2483 LoRa modem. As a standalone battery-powered node, the Mote provides a convenient platform to quickly demonstrate the long-range capabilities of the modem, as well as to verify inter-operability when connecting to LoRaWAN v1.0 compliant gateways and infrastructure.
The Mote includes light and temperature sensors to generate data, which are transmitted either on a fixed schedule or initiated by a button-press. An LCD display provides feedback on connection status, sensor values and downlink data or acknowledgements. A standard USB interface is provided for connection to a host computer, providing a bridge to the UART interface of the RN2483 modem. As with all Microchip RN family of products, this enables rapid setup and control of the on-board LoRaWAN protocol stack using the high level ASCII command set.

很多人拿到 Pi 3B+ 之後會迫不及待的把原本在 Pi 3B 上所使用的 SD 卡拿到 Pi 3B+ 使用，但是會發現無法開機。這是因為 Pi 3B+ 使用新的晶片(BCM2837B0)，因此如果沒有安裝 2018-03-13 以後所發布的核心(kernel)或是韌體(firmware)是無法直接使用的。
2018-03-13:
* Raspberry Pi 3 B+ support
* WiFi is disabled until wireless regulatory domain is set (Pi 3 B+ only)
- The domain can be done through 'Raspberry Pi Configuration' (rc_gui),
'raspi-config' or by setting 'country=' to an appropriate ISO 3166
alpha2 country code in /etc/wpa_supplicant/wpa_supplicant.conf.
$ sudo rfkill unblock wifi
$ sudo rfkill list

Pi 3B+ 這次新增了 MaxLinear MxL7704 電源管理 IC，可有更好的溫度管理策略。例如在 70°C 以下可以使用 1.4GHz 全速運轉；但超過了 70°C 就會降到 1.2GHz 的速度。可用 Sysbench 看溫度/頻率的曲線圖。
