Transistor Tutorial Summary Transistor Tutorial Summary Bipolar Junction Transistor Tutorial We can summarise this transistors tutorial section as follows: The Bipolar Junction Transistor (BJT) is a three layer device constructed form two semiconduct…

又入了一台打印机,171到手,本来之前有更好的,无奈别人下手太快,只剩这台了. 175x135x180的样子. 创客的板,还带16g的闪迪内存卡,看到那会儿感觉赚大了! 拿到的时候不少螺丝松的,有的打印件也裂口了,拧紧螺丝,调平后打了打感觉操作很多不习惯, 连上电脑看固件原来是marlin1.0的!上github下载了1.19固件,网上似乎没有找到关于hbot的配置贴, 反正以前琢磨过不少次,直接上configuration.h 凭借经验改了改,基本能用了.之后有待调试. 这个平台用料很足,3点…

The TPS54331 is a 28-V, 3-A non-synchronous buck converter that integrates a low RDS(on) high side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode™ feature is automatically activated. Furthermore, the 1 µA shutdown supply cur…

调节/测量放大电路电路图:PID控制电路图 如图是PlD控制电路,即比例(P).积分(I).微分(D)控制电路. A1构成的比例电路与环路增益有关,调节RP1,可使反相器的增益在0·5一∞范围内变化; A2是积分电路,积分时间常数可在22一426S范围内变化; A3是微分电路,时间常数由Cl(Rl+R(RP3))决定; A4将比例.积分.微分各电路输出倒相后合成为U. Controller Circuit This circuit is the basis of a temperature co…

BACKGROUND OF THE INVENTION Conventional NAND Flash memories move data in the background to write over an entire span uniformly. The background data movement is called wear leveling. A process performing the background data movement is often referred…
