The first board labelled "Arduino". Arduino USB [1] ATmega8 [52] 16 MHz Arduino 81.3 mm × 53.3 mm [ 3.2 in × 2.1 in ] USB FTDI FT232BM Arduino USB v2.0 Changed: USB replaces RS-232 interface, Improved: Arduino can be powered from host Arduino Extreme [1] ATmega8 [52] 16 MHz Arduino 81.3 mm × 53.3 mm [ 3.2 in × 2.1 in ] USB
USB 3.2, released in September 2017, [39] preserves existing USB 3.1 SuperSpeed and SuperSpeedPlus architectures and protocols and their respective operation modes, but introduces two additional SuperSpeedPlus operation modes (USB 3.2 Gen 1×2 and USB 3.2 Gen 2×2) with the new USB-C Fabric with signaling rates of 10 and 20 Gbit/s (raw data ...
Multi-Voltage Input/Output (MVIO) support on 3 or 4 pins on Port C; 4 Configurable Custom Logic (CCL) cells, 6 Event System channels; AVR EA-series. 8–64 KiB Flash; 28–48-pin package; internal 20 MHz oscillator; 24–32-channel 130 kS/s 12-bit differential Analog-to-Digital Converter (ADC) Programmable Gain Amplifier (PGA) with up to 16x gain
If all inputs are high, each buffer will be in a high-impedance state and the pull-up resistor will pull the output high. But if any input is low, the output will be pulled low by the buffer for that input. This corresponds to wired AND in active-high logic, or to wired OR in active-low logic, and allows multiple inputs to share the same output ...
12 V and 24 V powered USB sockets, on an NCR cash register. PoweredUSB, also known as Retail USB, USB PlusPower, USB +Power, and USB Power Plus, [1] is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter.
One USB 1.1 (LS & FS) controller and PHY, host and device support, 1.5 Mbps (Low Speed) and 12 Mbps (Full Speed) Two UART controllers; Two SPI controllers; One QSPI (quad SPI) controller (SSI), supports 1 / 2 / 4-bit SPI transfers, 1 chip select; Two I²C controllers; Eight PIO (programmable input–output) state machines; 16 PWM channels
7.2 Equipment intended for fixed installation with internal connections to the data link Fixed installation products with internal connections to the data link may use the 5-pin XLR connector, but shall not use any other XLR connector. When use is made of the 5-pin XLR connector, the requirements of 7.1 and 7.1.1 shall apply.
When at least one of the inputs is low, transistor V 1 is turned on, V 2 is turned off, V 3 is turned on and V 4 off, pulling output voltage high. When both inputs are high, V 2 is on, V 3 is off and V 4 is turned on, pulling output low. A digital use of a push–pull configuration is the output of TTL and related families.
