USB Mass Storage bootloader (based on UF2) for SAMD21 and SAMD51

LMIC-node | One example to rule them all. LMIC-node is an example LoRaWAN application for a node that can be used with The Things Network. It demonstrates how to send uplink messages, how to receive downlink messages, how to implement a downlink command and it provides useful status information. With LMIC-node it is easy to get a working node quickly up and running. LMIC-node supports many popular (LoRa) development boards out of the box. It uses the Arduino framework, the LMIC LoRaWAN library and PlatformIO.

⚡️Arduino E-Mail Client Library to send, read and get incoming Email notification for ESP32, ESP8266 and SAMD21 devices. The library also supported other Arduino devices using Clients interfaces e.g. WiFiClient, EthernetClient, and GSMClient.
