Reminder: 4418 core board can provide customers with after-sales and mass production services, but program customization is not accepted!
Product introduction
LQ4418 core board has as many as 180PIN pins, with strong scalability and operating speed up to 1.4GHz. The PCB adopts an 8-layer immersion gold process, which effectively resists interference and is stable and reliable in operation. This core board has a PMU onboard, which can be widely used in industrial control fields such as MID, POS, PND, PDA, mobile phones, game consoles, smart homes, laser burners, etc.
LQ4418 core board has the following features:
PMU uses AXP228 power management design to ensure stable and reliable work for a long time;
emmc, Toshiba 8GB emmc (19nm MLC process) is used by default, which can support multiple brands and multiple capacities;
Support power sleep wakeup;
Onboard Gigabit Ethernet;
