TO247 mos 80A is too high current, how to draw PCB?
The size of the vias, should the pads be enlarged?
When a current of 80A flows through a PCB, should we consider adding copper wires or copper plati...
Comparison of mainstream Rev2 Cortex-M3: ATMEL's AT91SAM3U4E and NXP's LPC1766. The Rev2 version of the CM3 core chip is very popular recently. The most mainstream ones are NXP's LPC1700 series and AT...
When electrons are driven by electromotive force in a closed circuit, they become current. The real voltage is the reaction force of impedance to the electromotive force. If the power supply has inter...
