Will the TTL pins on this GSM module be connected directly to AT89C51 microcontroller? robodude95 I plan on using this GSM module with an AT89C51 microcontroller and was wondering whether I needed an extra MAX232 chip since the module has Rx and Tx jumpers broken out. Are they TTL? Could they be directly interfaced with the microcontroller? I have circled the pins in question in the picture.
