The ESP32 has been a go-to microcontroller platform for a while now, thanks to its versatile capabilities, integrated Wi-Fi and Bluetooth connectivity, and low power consumption. It’s ideal for a wide ...

The Raspberry Pi is a great machine to learn the ins and outs of blinking pins, but for doing anything that requires blinking pins fast, you’re better off going with a BeagleBone. This has been the ...

Raspberry Pi owners looking to use higher voltages with their mini PC, might be interested in this new opto-isolator board called the Opto-pi which has been specifically designed to be used with the ...

Espressif yourself.

This paper provides a complete solution to the GPIO Verification for any SoC. GPIO interface is available in every ASIC. To avoid duplicate efforts and (save) time to verify the GPIO interface, we ...

How much can you cram into a 2.6 in x 1.2 in circuit board? You'd presume not much, but the Raspberry Foundation is trying to prove you wrong. First, it added built-in Wi-Fi to its teeny Raspberry Pi ...

This application note presents the CS4201/CS4202 audio codecs, and how to implement headphone jack sensing using the GPIO (general-purpose input/output) pins. It briefly introduced headphone jack ...

The 28c16 is an eeprom with 2048 bytes of storage. So, 11 address pins, 8 I/O pins, 3 mode pins and 5V and ground pins. Using just 6 gpio pins, my writer can write all 2048 bytes in just under a ...

Raspberry Pi enthusiasts looking for a quick way to add GPIO pins for prototyping that can be then easily removed once the project is finalised, are sure to be interested in a new PCB quick clip ...

Figure 1 shows the market size for VR and AR headsets, collectively referred to as extended reality devices, over recent ...
