Product Description
HW-537 Wireless GSM GPRS Module 5V 3.3V TTL single-chip pcba board 51 microcontroller IPEX SIM800C
Product Introduction:
| This module is designed with 5v/3.3v single-chip logic conversion circuit, because the GSM/GPRS core is 2.8v, which is different from the logic level of ordinary single-chip 3.3v or 5v. Many other development boards have not designed this part of the conversion circuit, which will cause damage to the MCU or GSM module for a long time. There are also some manufacturers who simply connect two resistors in order to save costs. This is also not advisable. In order to have a stable control system, logic level conversion is indispensable! |
