The BLDC Motor Driver Evaluation Board of the MCP8024 TQFP is used to demonstrate the MCP8024 drive capabilities. A total stand-alone engine operator for brushless DC motors (BLDC) is the MCP8024 TQFP BLDC Motor Driver Evaluation Board. The board is capable of riding up to 15A and 28V with a three-phase brushless DC motor. The board’s input voltage variety is between 7V and 28V. The MCP8024 on board uses internal rectifier diodes to produce 5V and 12V.

Motor gate driver MCP8024 3-Phase Brushless DC (BLDC)

The board uses the motor gate driver MCP8024 3-Phase Brushless DC (BLDC) and the plug-in module (PIM) dsPIC33FJ32MC204 to implement a 6-step BLDC motor controller. In a BLDC motor system, the MCP8024 TQFP BLDC Motor Driver Evaluation Board is being used to test the MCP8024 of Computer chip. As presented, the MCP8024 TQFP BLDC Motor Driver Evaluation Board is prepared to use one on-board toggle switch to stop and start the engine, plus one on-board potentiometer to set the engine speed. The test board will power a BLDC engine with up to 28V supply voltage and up to 15A motor current. The BLDC Motor Driver Evaluation Board MCP8024 TQFP offers a 6-step trapezoidal control dataset with a 750 mW buck converter, 5V and 12V LDO, high-to-low voltage translators, present sense operational amplifiers and Auditorium-effect inputs.The assessment board gives an impression of the designation of the power supplies and the six Pulse-Width Modulation (PWM) inputs on board.

Configuring the The MCP8024

The MCP8024 has setup registers which can be used to change the device’s operating variables. The parameters were changed using the DE2 messaging bus to transmit data to the MCP8024. The transmission bus DE2 is a half-duplex, 9600 baud, 8-bit data, 1-stop bit, 1-start bit, no parity, serial communication link. To communicate with the registers, the user can attach code to the firmware of the evaluation board. The code of the evaluation board includes a subroutine that initializes the registers of MCP8024.

Environmental Meter five in one

The environmental meter can be used measure humidity, temperature, airspeed, and air pressure assessment, both indoors and outdoors. It comes packaged alongside an advanced measurement converter, or a weather station. The weather varies from model to model. It automatically counts the dew point or store data on a computer for analysis following measurement. Environmental monitoring is critical to industrial processes, farming, housing and the health sector.

The Environmental Meter is an extremely good multi-function meter that combines the sound level meter functions, light meter, anemometer, moisture meter, and thermometer. It is suitable for a variety of environmental data collection needs and for indoor and outdoor applications. A backlit LCD screen displays current, high, and low readings, and has a data holding function.

Incorporated low friction vane wheel improves ft/min, MPH and m / s, km / h, air velocity accuracy, and knots. Built-in thin film precision sensor for fast response moisture sensor. They are built in a thermistor for the calculation of ambient temperature. Input type K measures 2372 ° (1300 ° C) temperature. They are using Cosine diode precision and correction filter and light-corrected color measurements. A frequency weight and rapid response time are used for sounds level calculation IEC 61672 class 2. Total with the thermocouple sample Type K, pouch, and six batteries of 1,5V AAA.

The meter is operated (included) by a 9V battery that lasts about 30 hours. In order to optimize battery lives, after 15 minutes of inactivity, the meter automatically turned off, and the low battery warning indicator informs you when power runs low.

Accurate and Reliable; consistently receive high-quality data and operate constantly. Set the meter away from objects with the tripod, which may affect the measurements of relative humidity.

Easy to use; Together with a backlit display, a ' lock ' feature to freeze readings, and well-marked control keys, this simple ergonomic meter works.

Inspect and troubleshoot; efficiently, the touch temperature sensor and wet bulb/dew point measurement operate on a broad range of systems more effectively.
