Nexperia NCA95xx I2C General-Purpose I/O (GPIO) Expanders provide an elegant solution when additional I/Os are needed while keeping the interconnections to a minimum. Housed in TSSOP24 and HWQFN24, these GPIO expanders are equipped with multiple features Interrupt, Hardware RESET,...

The ESP32 family of system-on-chips (SoCs) from Espressif now includes a new member. The RISC V-based ESP32-P4 has three processing cores, fifty general-purpose input/output (GPIO) pins, and a full complement of security options. Interestingly, though, the chip lacks the RF...

A USB hub that's also a dev board and an I2C, GPIO, and SPI bridge In addition to being a 4-port USB 2 High-Speed hub, this Programmable USB hub is also: A CircuitPython based development board. A bridge between your computer and I2C (via Sparkfun Qwiic connectors), GPIO, and...

Working with microcontrollers means managing GPIO pins at some point. Many configurations have been developed for modern microcontrollers which can lead to some “fancy” terms that may confuse programmers. Its important to understand all of this to avoid confusion and errors while...

BML project for using a $2 FTDI FT260Q for adding 14 bits of GPIO to any PC via USB with no device drivers required. Ever miss the simple days of using a PC’s LPT1 parallel port to bit-bang GPIO over 8 output pins and 4 input pins of the DB-25 connector? I sure do. My first design...

The Module is based on The MCP2200, which is a USB-to-UART serial converter which enables USB connectivity in application that have a UART interface. The device reduces external components by integrating the USB termination resistors. The MCP2200 also has 256-bytes of integrated user...
