SPIDER Automation Raspberry Pi 3 GPIO Board Multifunctional Cascade Expansion Extension Board
Description
SPIDER Automation Raspberry Pi 3 GPIO Board Multifunctional Cascade Expansion Extension Board is a GPIO expansion and access board designed for extending the Raspberry Pi 3 GPIO interface into additional connection points. The board provides another set of 2×20 pins along with 8 pins in parallel, allowing GPIO connections to be accessed through terminal blocks for wiring and testing.
The board provides terminal-block access for connections where test leads can be inserted directly. It incorporates two terminal blocks with 20 connections each and a press-to-release mechanism intended to make connection and disconnection of wiring convenient. The module also provides mini bridges that can be used to configure the GPIO connections according to the required setup.
The supplied characteristics include dedicated connections for TXD0, RXD0, 3.3V, 5V, GND, PWM, GPIO, PCM audio, CLK, SPI, MISO, SCE, and I2C-related interfaces. With its multifunctional GPIO access and expansion arrangement, the board is intended for Raspberry Pi 3 systems requiring additional accessible connection points for GPIO integration, wiring, and testing.
