PCB Design Considerations for RK3588 VDD_LOGIC Power Supply 1. The copper width for VDD_LOGIC must meet the current requirements of the chip. The copper connected to the chip’s power pins should be sufficiently wide, and the path should not be too severely interrupted by vias. It is essential to calculate the effective line width and … Read more
Recently, I watched a detailed explanation of circuit design by Philip Salmony, a graduate student from Cambridge University, on YouTube. The project is called the STM32-based RF to USB adapter, abbreviated as STRF, which includes: High-speed USB interface STM32L4 as the controller nRF24 2.4GHz RF transceiver Of course, he designed it using KiCad, and his … Read more
The Allwinner A64 64-bit processor, released in early 2015, features a quad-core Cortex-A53 architecture and a Mali400MP2 GPU. It supports H.265 4K video hardware decoding and runs Android 5.1. Primarily targeted at entry-level tablets, the A64 was designed for the 64-bit tablet market, but who buys tablets these days? Even my old iPad mini 2 … Read more
How to decide the layout and wiring on a board less than 16cm²? In the camera module design video released today, Director Chen from Zhibo Technology will take you further into the essential design principles of small PCBs. Through the explanation of this case, everyone will master the design methods of such small boards, eliminating … Read more
ESD: Electro-Static Discharge refers to the release of static electricity. Static electricity is a natural phenomenon that usually occurs through contact, friction, or induction between electrical devices. It is characterized by long-term accumulation, high voltage (which can reach thousands or even tens of thousands of volts), low charge, small current, and a short duration of … Read more
