A Hardware Bug in the RP2350 microcontroller family causes GPIO pins to get stuck at around 2.15V when configured as inputs with internal pull-down resistors. This "latching" behavior is due to a faulty fault-tolerant pad design from an unnamed IP vendor. The issue affects all GPIO...

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...
