16MHz Crystal Oscillator HC-49S – Quartz Crystal for Arduino, AVR & Microcontroller Clock
The 16MHz Crystal Oscillator in the HC-49S package is a fundamental timing component for digital electronics and microcontroller circuits. This quartz crystal provides a precise 16.000 MHz clock signal that serves as the heartbeat for your microcontroller projects. It is the exact same frequency used by the Arduino Uno (ATmega328P), Arduino Nano, and countless AVR-based development boards, making it an essential spare or prototyping part for every electronics enthusiast, engineering student, and IoT hobbyist in India. The HC-49S is a low-profile, through-hole package that is easy to solder onto perfboards, stripboards, and custom PCBs. Unlike the taller HC-49/U variant, the HC-49S sits closer to the board, saving vertical space in compact enclosures. This crystal works with the internal Pierce oscillator circuit built into most microcontrollers — simply connect it across the XTAL1 and XTAL2 pins with two load capacitors (typically 22pF each) and your MCU will run at a rock-solid 16 MHz. Why keep a few of these in your component bin? Crystals can get damaged from physical shock, overheating during soldering, or electrostatic discharge. If your Arduino suddenly stops responding or behaves erratically, a dead crystal could be the culprit. Swapping in a fresh HC-49S 16MHz crystal is a quick, low-cost repair that can bring a dead board back to life. These crystals are also perfect for building standalone ATmega328P circuits on a breadboard — the classic "breadboard Arduino" project that every Indian engineering student tackles in their second or third year. Beyond Arduino, the 16MHz HC-49S is used in digital clocks, frequency counters, RF circuits, USB-to-serial converters, and any application that demands a stable, accurate timebase. TecnoMate sources these crystals from reliable manufacturers with tight frequency tolerance so your projects run reliably, semester after semester.

Arduino 2.4" TFT LCD Touch Shield – 240×320 Color Display with Touch & microSD
The Arduino 2.4" TFT LCD Touch Shield is a feature-packed display shield that snaps directly onto your Arduino Uno or Mega2560, instantly giving your project a vibrant, interactive graphical interface. With a 240×320 pixel resolution and 18-bit color depth capable of rendering over 262,000 distinct colors, this shield transforms any Arduino project with full-color menus, gauges, graphs, buttons, and touch-driven user interfaces. At its core, this shield uses a proven TFT driver IC — either the widely supported ILI9341 or the SPFD5408 controller (depending on the manufacturing batch) — both of which have mature, open-source libraries available in the Arduino IDE (Adafruit_ILI9341, Adafruit_GFX, MCUFRIEND_kbv, and UTFT). You can draw shapes, display bitmap images, render custom fonts, and plot sensor data with just a few lines of code. The resistive touch screen overlay detects finger or stylus input across the entire 2.4-inch active area, allowing you to build touch-controlled menus, on-screen keypads, home-automation dashboards, and interactive games. One of the shield's standout practical features is the onboard microSD card slot. This lets you store large image files, data logs, configuration files, or even full bitmap UI assets directly on a removable card — freeing up precious Arduino flash memory. The shield is powered directly from the Arduino's 5V rail and includes an onboard 3.3V LDO regulator (300mA) that supplies the TFT panel and SD card. Note that while the shield accepts 5V supply, the TFT logic operates at 3.3V — most shields include resistive voltage dividers or buffer ICs on the data lines for basic level adaptation, though it's wise to verify your specific variant's level-shifting implementation. Pin usage on a typical Uno-compatible shield: the 8-bit parallel data bus occupies D2 through D9, with control lines on A0 (RD), A1 (WR), A2 (RS), A3 (CS), and typically A4 (RST). The microSD card communicates via the hardware SPI bus on D11 (MOSI), D12 (MISO), D13 (SCK), with chip-select on D10. The resistive touch panel's analog readout uses a subset of the analog pins shared with the control bus. This pin mapping means D0 (RX) and D1 (TX) remain free for serial communication, and A5 (SCL) is usually free for I²C clock — making it possible to add certain external sensors alongside the shield with some planning. Whether you're building a weather station dashboard, a portable oscilloscope, a home automation control panel, an arcade game, or a data-logger with live graphs, this shield brings professional-grade visual output to your prototype without the cost and complexity of external monitors. It's one of the most popular Arduino display shields in the Indian maker community, widely used in engineering college projects, IoT prototypes, and STEM education kits.
