The board in this article is not a dedicated board limited to a specific communication standard. The basic policy is to first build a stable 8-input/8-output I/O board using the ESP32-C6 + MCP23017, ...

Optocouplers frequently fail without a sound in labs or during repairs. The package appears to be undamaged, but there may be no output from the LED source or the photosensitive output stage. Testing ...

ESP32_Host_MIDI turns an ESP32 into a multi-protocol MIDI hub. Connect a USB MIDI keyboard over USB Host, receive notes from an iPhone over BLE, bridge a DAW over WiFi with RTP-MIDI (Apple MIDI), talk ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

The difference between high-side and low-side power switching is not apparent to many new designers but is a critical aspect of a viable circuit. Part 1 looked at the topology of high-side versus ...

After the success of PicoADK v1, Datanoise has recently announced the launch of its PicoADK v2 music synthesizer built around the Raspberry Pi RP2350 MCU. The board supports projects like custom ...

Waveshare “ESP32-S3-Touch-LCD-4.3B” is a capacitive touch display development board built around an ESP32-S3 SoC with RS485, CAN Bus, I2C, and isolated DIO interfaces provided through a terminal block ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
