Do we want nano SIMs?


Initial Design Layout for B3.01

We’re currently re-designing the twin output relay board which up to now has had no input.  It’s also a pretty old design (>2 years which is amazingly geriatric in the GSM industry) so is well in need of updating.  It’s tempting to go quite radical as we could add Bluetooth quite easily for number setup but that may have to wait.

What we would love to know is whether you as an installer want to see a nano SIM holder yet.  The larger micro SIM is becoming less common and I frequently find callers to the office have no means of fitting the dialer/gate opener SIM in their own mobile for registering/testing.  Do you want to see our products with a nano SIM holder?

Advent Controls A3.02

It is likely, as these boards have some crossover in terms of application, we will put the nano SIM on this board and the full size SIM on the 1-out 2-in board and see which users prefer.

Please leave your thoughts in the comments they would be very much appreciated! (click leave a reply at the top)

    Logical move to go ‘nano’ SIM but would suggest including a full-size SIM converter (available for less than £1 each retail) to avoid any issues. Surely then would be all things to all people!

    The current PCB being designed at the moment has two outputs and one input. The ‘A’ boards have two inputs and one output. These will be available during December.

    I now use your old device. But I haven’t enough 1 relay and 1 input… I want to buy other controler of other firm with a large number of the relay and inputs, but in your device I like its reliability (two seasons of work in hot conditions).

    always i used to read smaller posts that as well clear
    their motive, and that is also happening with
    this paragraph which I am reading now.
