Arduino Development Board MKR GSM 1400, SIM 2G 3G Cellular Network, ATSAMD21

\"The Arduino MKR GSM 1400 is a great starting point for building IoT projects connected to GSM / 3G network. Whether you are looking at building a sensor network for agricultural projects, or for urban data collection, the MKR GSM 1400 is your go-to board for IoT projects when Wi-Fi® is not available.\" Tons of details at: considers this device \"End of Life,\" presumably because the 2G and 3G networks the modem can connect to are being shut down. This device was in service for me, using connected sensors forremote monitoring of about a dozen metrics,until August, 2026 when the nearby network was shutdown and it could no longer connect. But there are other parts of the world where these networks will be kept running for several years. Or, use it as a regular Arduino MKR board that just doesn\'t have GSM capabilities if you project doesn\'t need that.
