What are GND pins?
GND is short for ground. All integrated circuits have a ground pin which should be connected to circuit board ground. For a stight digital board with just one supply voltage, Vcc or Vdd for example, ground connects to the negative terminal of the power supply.
How many GPIO pins are in Beaglebone black?
69
For a reasonable price you get some really nice hardware specs: 512MiB RAM, 1GHz AM335x ARM with an FP accelerator, 4GiB on-board flash AND and external SDcard slot, Ethernet, USB-Host, HDMI, 2 on-board programmable microprocessors (the PRUs) and last but definitely not least: 69 digital GPIO pins and 7 analog inputs …
What is VCC?
VCC (Voltage Common Collector) is the power supply of a device . Ground is the the reference point against which the VCC is compared. It can be positive or negative compared to GND. When the VCC is at zero colts, it is called the ground.
What is beagle bone black?
BeagleBoard BeagleBone® Black is a low-cost, community-supported development platform for developers and hobbyists, based on the Sitara AM3358BZCZ100 Arm Cortex-A8 32-Bit RISC microprocessor from Texas Instruments.
Does GND mean ground?
What Does Ground (GND) Mean? Ground, in the context of electronics, is the reference point for all signals or a common path in an electrical circuit where all of the voltages can be measured from. This is also called the common drain since the voltage measurement along it is zero.
What is the voltage on this pin in BeagleBone Black?
The voltage on this pin will be 5 volts but the current will depend on the power input. All these pins are multiple in numbers and all of them are given below: Ground: Every two devices need a common ground to operate and BeagleBone Black has multiple of them.
How do I connect my BeagleBone Black hardware to my Device?
Do not connect BeagleBone Black hardware directly to devices that use higher voltages. To receive data, connect the P9_26 (UART1_RXD) pin on the BeagleBone Black hardware to the TxD pin on the serial device. To transmit data, connect the P9_24 (UART1_TXD) pin on the BeagleBone Black hardware to the RxD pin on the serial device.
What are the eccappwm pins in BeagleBone Black?
ECAPPWM pins are limited in number in BeagleBone Black and all of them are listed below: It is a port used for multi-channel serial applications. It uses the sperate clock, data and frame sync pin. In Beagle Bone the MCASP pins are in P9 Header which is given below: It stands for a multimedia controller.
How many internal timers does BeagleBone Black provide?
BeagleBone Blacks provide the four internal timers which are being used according to the external pulse input pins. All these pins are in P8, which are given below:
