The Digilent Pmod interface is used to connect low frequency, low I/O pin count peripheral modules to host controller boards. There are six-pin and twelve-pin versions of the interface defined, encompassing SPI, I²C, UART, I2S, H-bridge and GPIO protocols. The six-pin version provides four digital I/O signal pins, one power pin and one ground pin.

Pmod is short for “peripheral module” and these modules are specifically designed to extend the capabilities of embedded systems and development boards by adding new features and functionality. Pmods communicate with host boards using 6, 8 or 12-pin connectors that can carry multiple digital control signals, taking advantage of standard ...

Pmod interface (peripheral module interface) is an open standard defined by Digilent in the Pmod Interface Specification [1] for connecting peripheral modules to FPGA and microcontroller development boards using 6 pins. Pmod or Pmods may …

2022年3月9日 · Pmod接口标准是由Xilinx的第三方合作伙伴迪芝伦（Digilent）制定的接口扩展规范。 它主要针对低频，少引脚外围模块。 接口定义了6 脚和12脚接口。 6脚版本定义了4 个数字IO和一个电源，一个地线。 12 引脚版本定义了8个IO信号脚，一对电源脚和一对地线。 pmod 定义了下面几种类型. FPGA 夹层卡 (FMC) 标准由包括 FPGA 厂商和最终用户在内的公司联盟开发，是美国 ANSI 标准。 FMC 主要是高速，多引脚模块定义的接口。 从引脚的数量分，FMC 分为. …

The six-pin version p rovides four digital I/O signal pins, one power pin an d one ground pin. The twelve-pin version p rovides eight I/O signal pins, two power pin s and two ground p ins.

The PMOD connector is based on the standard 0.100" (0.254mm) pin headers in either 6 or 12 pin configuration. There's a few other recurring themes: Both host and module ports are typically right-angle at the edge of the board.

Pmod peripheral modules are pow ered by the host via the interface’s power and ground pins. The Pmod interface is not intended for high frequency operation, however, using RJ45 connectors and twisted pair Ethernet cable, signals have been sent reliably at 24M hz and distances of up to 4

Typical Pmod peripherals include sensors (voltage, light, temperature), communication interfaces (Ethernet, serial, WiFi, Bluetooth), and input and output interfaces (buttons, switches, LEDs). Each Pmod connector has 12 pins arranged in 2 rows of 6 pins. Each row has 3.3V (VCC), ground (GND) and 4 data pins. Using both rows gives 8 data pins in ...

The 6-pin configuration consists of four pins, pins 1, 2, 3, and 4, that are to be available for the communication protocol. The remaining two pins, pins 5 and 6, are to act as the ground and power pins. The 6-pin configuration is commonly used in protocols such as SPI or UART which only require 4 communication pins to operate.

There are level shifters on the PMOD connections. The connector side is at 3.3V, FPGA pins connected to J52 are powered by VADJ_1V8_FPGA and the FPGA pins connected to J53 are powered by VCC1V2_FPGA. The PMOD connectors expect 3.3V and the level shifters convert to 1.8V CMOS or 1.2V CMOS.
