Summary of The Arduino compatible MicroLink
The MicroLink is a USB plug-and-play, Arduino-compatible board combining an ATmega328 microcontroller with a SIM800H quad-band GSM module, offering cellular data, calls, SMS, battery charging, and USB connectivity for remote monitoring and control and alerting from nearly anywhere.
Parts used in the MicroLink:
- ATmega328 microcontroller
- SIM800H quad-band GSM module
- On-board USB interface
- Battery charging circuitry
- USB plug-and-play connector
Tiny self-contained board that can do automation, alerts, cellular data, phone calls, SMS text messages, and more – USB plug & play
Electronics News:
“users can use the MicroLink as the basis for systems that can monitor and control nearly anything, from any phone, from nearly anywhere in the world.”

Atmel Corporation:
“MicroLink is like a tiny Arduino with GSM. … An ATmega328 allows for constant control, while a SIM800H quad band GSM module makes communication with wireless devices simple. … One of the most unique features of the MicroLink is that it comes ready to use out of the box with a true plug-and-play dynamic”
In addition to GSM and Arduino compatibility, the on-board USB and battery charging capabilities also give the capacity to implement professional quality wireless remote-monitoring and remote-control – all with USB Plug & Play simplicity.
You get the latest SIM800H quad band GSM module on board with an ATmega328 microcontroller, so you’re able to monitor and control nearly anything, anywhere – all with the freedom and immediate usability of an Arduino compatible.
