Standard module means the software of the module supports standard AT command which doesn t support OpenCP U function OpenCPU module means the software of the module supports OpenCP U function Customers can make secondary development based on the module download and run customer software After the module is powered up besides its own software you can also load customer software Module Firmware means the software comes with the module usually it is already downloaded by default Customer Software means the secondary development software usually customer need to download it to the module Some interface definitions of the module are different due to different software This document is based on G510 Hardware User Manual and G5 Family OpenCPU API User Manual it introduces some methods and notes of hardware interface design and functional design when you use OpenCPU module G510 Hardware OpenCPU User Manual Page 5 of 14 Bs FIBOCOM 1 2 OpenCPU features Item G510 Base Band RDA8851 MIPS 208MHz Flash Code Space BYTE 512K Flash Data Space BYTE 512K Hardware RAM BYTE 512K UART 3 GPIO 5 INT 2 No limits with file number File storage space is File System 512k each file cannot exceed 100k Unit ms Chigher than 500ms is recommended Software Timer You can enable at most 25 software timers at the Sonwane same time Thread 5 Watchdog Supported
