Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried!

This breakout is best used for projects such as voice changers, audio recording and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6" away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp!

Using it is simple

Connect GND to ground, VCC to 2.4-5VDC.
For the best performance, use the "quietest" supply available (on an for Arduino, this would be the 3.3V supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an audio amplifier (such as 3.7W stereo amp) if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUT pin directly to the microcontroller ADC pin. For audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies.

Note: This logic level shifter breakout comes with loose headers. You will have to solder them yourself.

If you have ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be! The logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. Each level converter can convert 4 pins on the high side to 4 pins on the low side, with power supply pins on each side.

The usage of the level converter is very straightforward. The board needs to be powered from the two voltage sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the "HV" pin, low voltage (3.3V for example) to "LV", and ground from the system to the "GND" pin.

This module requires you to supply it with power from both the higher voltage level and the lower voltage level. Connect the higher voltage source to pin "HV" and its ground to pin "GND" near the "HV" pin. Also, connect the lower voltage source to pin "LV" and its ground to pin "GND" near the "LV" pin.

For example, if you were connecting your Arduino (5V signals) to an ESP8266 (3.3V signals), you would connect the "HV" pin on the module to the 5V supply pin on your Arduino and the "GND" pin near the "HV" pin to the "GND" pin on your Arduino. Then, you would connect the "LV" pin on the module to the 3.3V power source that is supplying power to the ESP8266 and connect the "GND" pin near the "LV" pin to the 3.3V power supply's ground. You would then connect the signal pin from your Arduino to one of the signal pins on this module (for example, pin "HV1"), and then you would connect the desired signal pin on the ESP8266 to the corresponding pin on this module ("LV1" if the higher voltage signal is connected to "HV1").

These are 4 Channel devices (works great for I2C or SPI) and will work with all microcontrollers, Arduino, Raspberry Pi, Intel Edison, etc. Use this module to connect two devices of different digital voltage levels. For example: connecting an Arduino (5V device) to an ESP8266 (3.3V device).

The logic level converter comes complete with loose header pins and can be used directly on a breadboard.

The LD2410C is a high-sensitivity 24GHz millimeter-wave (mmWave) radar module designed for advanced human presence detection. Unlike traditional PIR sensors that only detect movement, this FMCW (Frequency-Modulated Continuous Wave) radar can sense the tiny chest movements of a stationary person (breathing), making it the ultimate solution for "smart room" occupancy.

Why choose mmWave over PIR?

• Stationary Presence: Detects sitting, standing, and even lying down. Your lights will never turn off while you're reading or watching TV again.
• Environmental Immunity: Not affected by temperature, light, smoke, or humidity.
• Invisible Installation: The radar can penetrate plastic shells and glass, allowing it to be hidden inside a project box or behind a thin wall for a clean aesthetic.

Key Features

• Long-Range Sensing: High-precision detection up to 5–6 meters.
• Wide Coverage: Broad ±60° detection angle ensures full room coverage.
• Smart Tuning (Bluetooth & Serial): Easily configure "Gate" sensitivity, distance zones, and delay times via the HLKRadarTool App (iOS/Android) or a serial debugging tool.
• Fine-Grained Zones: Divide the sensing range into intervals and shield interference from objects outside the target area (e.g., a fan or a window).
• Compact Design: Ultra-small footprint (16mm x 22mm) for easy integration.
• Wide Voltage Support: Reliable performance with a 5V to 12V power supply.

Technical Specifications

• Operating Frequency: 24GHz (ISM Band)
• Detection Type: Motion, Micro-motion (Breathing), and Stationary Presence
• Voltage: 5V – 12V (Average current ~80mA)
• Output: High/Low GPIO (3.3V Logic) and UART Serial (256,000 baud)
• Mounting: Supports Ceiling or Wall mounting
• Regulations: FCC and CE compliant

Ideal Applications

1. Smart Lighting: Energy-saving control for homes and offices.

2. AIoT Wake-up: Automatically wake up advertising screens or tablets when a person approaches.

3. Safety & Security: Detect intruders or prevent UV lamps from turning on while people are present.

4. Smart Appliances: Power down TVs or Aircons when a room is truly unoccupied.
