Please make sure you have 2G network coverage, these will not work on 3G or 4G, thank you.
My new PCB's arrived today and I can finally build some of these little GSM alarms.
Updated the pictures showing the new version. Will upload a new video soon.
Quad Band GSM / GPRS Dialer and SMS Sender with OLED Display and custom Software All display colors are currently on stock. Please let me know your choice. Thank you.
I have all these ideas that I try to bring to life one by one. This was on my list for a long time.
It is custom made based on my OLEDiUNO PCB with software written by me and tweaked each pixel so it does look great too.
You can use this in many ways. You can program it to send SMS messages, call phone numbers, use it as a alarm in your home or everywhere you can attach a battery. It runs between 3.6 - 4.2 Volts. You can easily reprogram it using my USB to TTL adapter with Pogo pins.
For more info please get in touch with me using the 'Contact me' on the right hand side.
My example code will be supplied of course.

I build the best Atmega328 based micro OLEDiUNO PCB that enables you to connect a I2C OLED display directly to the PCB. Plus the OLEDiUNO PCB features an on board navigation switch and 2 slide switches and or push button switches and 4 smd LED's in each corner front and back, totaling to 8.
Also build the best Grbl based CNC Controller with PWM output, spindle enable and coolant outputs among other features not found on any Arduino shields.
