What is pi E9U6?

Fri Feb 02, 2018 7:33 pm

Hello, I found the gsm module on eBay, https://www.ebay.com/itm/SIM900-Module- ... 0011.m1850

It says for pi E9U6, what is piE9U6? is it pi 3, pi2? Thanks.

The E9U6 does not refer to the RPi. Most likely explanation I can come up with is that it refers to the physical footprint of the board (in centimetres).

Thanks for the reply.
Do you think this GSM module is compatible with pi 3? I emailed the seller, but he refer it back to the ad, I just want to be sure it will work on the pi3.

Probably compatible in the sense that it can be made to work with a RPi but not plug and play. I've never used one of these SIM900 things so cannot advise. I do recall some posts on the forum. Have a search here and on the internet generally and see what you can find.

My Google-foo led me to these: So firstly there seems to be guidance on how to use modules like or similar to the one you're looking at. Secondly it would appear that there are SIM900 modules designed specifically for the Raspberry Pi, and it might be prudent to get one of those.

The only concession they have seemed to have done is to add jumpers so that the serial RX signal is resistor divided so it doesn't put 5V on the RxD pin of the Raspberry PI, and they made the board size such that it did fit on the original PI model 1, but not on the later models (except perhaps the zero).

That original link seems to point to a module designed and intended for an Arduino with "Raspberry Pi" probably added to attract attention. No idea what "E9U6" references.

If you know what you are doing you can probably get it working with a Pi. That you are asking suggests that you don't and it would probably be better to get something designed and intended for the Pi, has details of how to configure and use it with a Pi.
