Take others, these didn't suit me.

editing my review. Having just posted a one star review describing that the two devices I received didn't work and the same SIM800L chips worked with a different form factor, I tried the two devices again and they worked . I'm not sure what happened, I swear I've been trying for the last 3 days running the same AT commands and they just didn't register on the network but now they do. One star off because I couldn't get it to work for 3 days. Maybe you're less lucky.

Pros

TTL serial port for serial port, can be connected directly to the microcontroller

Cons

old
