  IoT and Wi-Fi Internet of Things (IoT) is rapidly growing across the globe. Its application is now broadening into the various sectors of the economy from manufacturing to agriculture. Wi-Fi has played a critical role in this growth.  IoT applications  have numerous connectivity requirements with regards to data throughput, energy efficiency range, and cost of the device. Wi-Fi has often been an obvious choice. This can be attributed to the many reasons as discussed below; Pros and cons of Wi-Fi Pros Flexible- It offers high integration thus is ideal for consumer products Highly convenient – Wi-Fi can be used with a wide range of portable devices anywhere within the premise Globally standardized – Wi-Fi enabled devices can connect to Wi-Fi anywhere in the world. A popular choice –  Wi-Fi  is a popular option amongst consumer electronics manufacturers and consumers as well. Range – Wi-Fi has a decent range coverage and can penetrate through walls and other obst...

  The   MCP8024 BLDC Motor   Driver Evaluation Board is used to show the drive capabilities of the MCP8024. The board incorporates the MCP8024 3-Phase BLDC motor gate driver and dsPIC33FJMC204 PIM to actualize a 6-step trapezoidal BLDC motor control. This board is used to evaluate the applications of the   MCP8024 Microchip   MCP8024 in the BLDC motor application. The board can drive a BLDC motor using a single onboard push button to start and stop the moto and one onboard potentiometer to set the motor speed. The MCP8024 is capable of driving a BLDC motor with a supply voltage of up to 28V and a current of 15A. It has a 6-step trapezoidal control algorithm coupled with5V and 12V LDO, high-to-low voltage translators, current sense op-amps, 750 mW buck converters, and Hall-effect inputs. Features Input voltage range of between 7 and 28V 500mA gate drive current Drives BLDC motors of up to 15A 750 mW Buck regulator (with resistor-programmable output voltage) ON/OF...

  Zero-ohm resistors A Zero-ohm resistor is simply a  resistor  with zero ohms. It’s a through-hole resistor that has been manufactured to have zero ohm of resistance and is marked with a single black band.  A surface-mount ceramic resistor has single or multiple numbers of zeros to represent the zero-ohm resistance. It is pretty much like a jumper wire that is shaped like a resistor. Why do you need a zero-ohm resistor? Why not just use a jumper? Uses of a Zero-ohm resistor. An alternative for jumper wire The use of jumpers in circuits is common. They allow for unmatched flexibility. However, they are only applicable if you are going to solder manually. That is not the case in mass production. Mass production involves pick-and-place machines which do not have the ability to handle jumper wires. An extra machine would be required for that making the cost of production to rise. To avoid that, a zero-ohm resistor is used. It saves both cost and assembly time. More can ...
