MikroTik – CME22-2N-BG77 – CME Gateway – IoT gateway with 650MHz CPU, 64MB RAM

Tired of the limitations of wired sensors? Wouldn’t it be nice if older devices – like electricity meters – could send their data over the mobile network, just like our phones do? With the CME gateway, you can do just that – and more!

It has two Ethernet ports, an integrated CPU, some RAM and the crown jewel: a powerful integratedCAT-M narrowband LTE modem. For an extremely efficient, low-cost, low-bandwidth mobile internet connection. Sure, narrowband can’t be used to stream YouTube videos, but it serves another purpose: it provides better network coverage and transmits data via the world’s cheapest data tariffs.

Thanks to its IP66 waterproof rating, the rugged device cansurvive a variety of harsh environments and setups: damp attics, rainy forests, agricultural equipment and so on. It has a PoE input, a PoE output and a 2-pin DC connection fora convenient power supply. And to make management even easier, we’ve added a simple single-chain 2.4 GHz wireless so you can use the MikroTik smartphone app to configure everything.

Another fun bonus: The board supports GPS. So if you know your way around RouterOS scripts, you can also collect weekly, daily or even hourly location data!
