Smart Machine Smart Decision Users can power on SIM5800 by pulling down the PWRKEY pin at least 6 seconds (TBD) and then release. This pin is already pulled up to VBAT in the module, so external pull up is not necessary.

Smart Machine Smart Decision 1. 2. In the download phase, the current limit is very small from the VCHG to the VBAT path , only enough for the module to download the required current. Therefore, normal startup function of the module cannot be realized through VBUS power supply. If there are other chips in the module VBAT network which will consume the current when the power on, if the current consumption is high, it will also cause the module download failure. 4.5.

Smart Machine Smart Decision Figure 19: Charge diagram Note: The standard charger supported by SIM5800 module needs to connect USB_DP and USB_DM together, and the charging current can only reach the normal value set by the software after the software determines that it is a standard charger. If there is no short connection between USB_DP and USB_DM, the software thinks that it is a non-standard charger with a small charging current and a slow charging. 4.6.

Smart Machine Smart Decision 5. PCB Layout Guide Usually, most electronic products with good performance are based on good PCB layout. A bad PCB layout will lead to lots of issues, like TDD noise, SIM card can not be detected, etc. The final solution for these problems is to redo PCB layout. Making good PCB layout at beginning will save development schedule and cost as well. This section as below will give some guidelines on PCB layout. 5.
