A PWM-capable fan is usually connected to a 4-pin connector (pinout: Ground, +12 V, sense, control). The sense pin is used to relay the rotation speed of the fan and the control pin is an open-drain or open-collector output, which requires a pull-up to 5 V or 3.3 V in the fan.
This is a special variant of the Molex KK connector with four pins but with the locking/polarisation features of a three-pin connector. The additional pin is used for a pulse-width modulation (PWM) signal to provide variable speed control. [26] These can be plugged into 3-pin headers, but will lose their fan speed control.
up to 4 x PWM; 2 x ADC (8 bit) 1 x 40-pin LVDS + eDP connector. 1 x 5V Panel Backlight & Control header. 1 x IR Receiver header. 1 x 2-pin Recovery header. 1 x 4-pin Power-on & Reset header. 1 x 3-pin Debug UART header. 1 x 4-pin DC Fan header. 1 x 2-pin RTC Battery header. 1x CAN Bus 2.0B FD pin header. 2x COM 232 (with flow control) pin ...
A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...
STEMMA: by Adafruit, utilizes 4-pin JST PH 2.0mm connectors (3-pin connectors are meant for analog/PWM use) [33] pinout: GND, Vcc (3V–5V), SDA, SCL Grove : by Seeed Studio , utilizes 4-pin 2.0mm proprietary connectors, known as A2005 series, or 1125S-4P [ 34 ]
DC brushless ducted fan. The two coils on the printed circuit board interact with six round permanent magnets in the fan assembly. A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply.
The Platform Controller Hub (PCH) is a family of Intel's single-chip chipsets, first introduced in 2009. It is the successor to the Intel Hub Architecture, which used two chips–a northbridge and southbridge, and first appeared in the Intel 5 Series. The PCH controls certain data paths and support functions used in conjunction with Intel CPUs.
In automotive electronics, body control module or 'body computer' is a generic term for an electronic control unit responsible for monitoring and controlling various electronic accessories in a vehicle's body.
