The Milk-V Duo 256M is a compact board powered by the SOPHGO SG2002 SoC, integrating multiple architectures including Arm, RISC-V, and 8051. It has 256MB of built-in RAM and a 1 TOPS neural processing unit (NPU) for advanced computations. For storage, it features a microSD card slot....

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,...

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...

Measurement Computing Corporation (MCC) has released a $99 measurement DAQ (Data acquisition system) HAT for the Raspberry Pi. It is highly optimized for single point and waveform voltage. MCC claims their board allows greater accuracy with high resolution. It has much faster sample...

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...

Even if you have years working with electronics, you will still find some simple hacks that you never thought about before. Personally and to save money, when I was a student with a very limited budget I knew that my Arduino UNO can work as a USB/TTL(serial) converter. I used to remove...
