I was wondering whether it's possible to use the mini GSM800L module with an ESP8266-01. The GSM800L works with Arduinos, and I know I can program the ESP module in the Arduino IDE. I'm just not sure if the module itself is compatible, and how I would go about getting it to work.

Any help would be much appreciated.

Thanks

But if it's 5V UART, you will need converter. Check the datasheet to be sure.

Thanks for your help . I'll give it a shot and see if it works.

A development board is equally cheap at around $2 to $3 a piece, but will make your life so much easier in a development stage.
Of course it's fine to use a module in your final design, there's nothing wrong with that, just get all the uncertainties out of the way while developing.

See my signature below for some sources (I'm not affiliated with any of the sellers, I regularly just try to find the cheapest suppliers and update the links accordingly).

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
