Adding a speaker to an embedded project is not always as simple as connecting it directly to a microcontroller or single-board computer. Most audio sources provide a relatively low-level signal, while a speaker needs more power to produce useful sound output. This is where an audio amplifier becomes important. The PUI Audio AMP2X15 is designed to bridge this gap,…
Vision development boards are useful when an embedded project needs to combine image capture, local display, audio input, storage and wireless connectivity in a single platform. The ESP32-P4X-EYE takes this approach around the ESP32-P4, adding an ESP32-C6 wireless module, a 2MP MIPI-CSI camera, a 1.54-inch SPI LCD, a digital microphone, MicroSD storage, USB…
Bluetooth trackers like Apple AirTags and Samsung SmartTag are a convenient way to locate misplaced items nearby, but their dependence on nearby smartphones limits their usefulness over long distances. Cellular GPS trackers overcome this limitation by communicating directly over the mobile network, allowing them to report their location from anywhere with network…
Bluetooth Low Energy (BLE) has become one of the most widely adopted wireless technologies for battery-powered devices, offering reliable communication while consuming only a fraction of the power required by traditional wireless protocols. From wearable electronics and healthcare devices to wireless audio accessories and industrial sensors, BLE enables devices to…
This is the teardown tutorial of ESP32-2424S012C, an ESP32 C3-based development board with an integrated display. This device comes in very handy, as it has our favourite ESP32-C3 onboard, a 1.28” IPS Capacitive Touch Screen display with a 240×240 px resolution. The coolest thing about this is that it can be custom-programmed to our specifications using a wide range…
The MAX32672FTHR is a compact development platform built around the MAX32672 for embedded evaluation and prototyping. It provides the key hardware resources needed for development, including onboard debugging, power management, user interface peripherals, and Feather-compatible expansion headers.
With many essential components…
The E88 quadcopter drone is a consumer-grade quadcopter drone designed for indoor and outdoor recreational flying. Featuring a foldable design, a WiFi camera, and altitude-hold capabilities, this detailed E88 drone teardown represents a typical entry-level drone in the sub-₹2000 market segment. The drone's compact…
For wearable projects, having the right sensor module makes all the difference. As you all know, this year’s contest theme is Smart Home and Wearables, so we came up with another sensor module, the MAXREFDES117 optical heart-rate module. This device comes with integrated red and IR LEDs, making it an ideal choice for developers and enthusiasts alike. The MAXREFDES117…
There have been many development boards recently built around the ESP32-S3. Most development boards come with a display, some also include cameras and buttons, and a few have speakers and microphones. Finding one that brings all these components together without compromising on quality has been the real challenge for makers and developers. Keeping all this in mind,…
If you are an embedded hardware engineer who is into product designing, then you must be aware about the importance of understanding the power consumption by each and every part of your circuit in order to validate and optimize your circuit. Nordic’s Power Profiler Kit II is a device essential for validating and optimizing the performance of your…
Are you a DIY or an IoT or enthusiast who is planning to start their voyage into the mysterious lands of embedded systems or someone who is planning to up their game from an “8-bit microprocessor” to something more powerful? Or maybe, you are a seasoned engineer, in the proof of concept phase, deciding on a module for prototyping your next consumer grade product and trying…
The ESP32 microprocessors from Espressif have quickly gained popularity and can already be found being used in many IoT projects which requires Wi-Fi or BLE Connectivity. While these processors pack in a lot of power it is often difficult to program them in the native environment for beginners and IoT enthusiasts. To tackle this problem and speed up IoT development…
