Description: For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples/second over I 2 C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter. The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I 2 C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1015's connected on a single 2-wire I 2 C bus for 16 single ended inputs. Package included: 5 x Analog-to-Digital Converter  

Description: Power to other devices by power Bank. Such as: routers, USB lights, USB fans, radiators, 5V mini speakers, etc. Outer diameter: 5.5mm, inner diameter: 2.1mm; Inner positive, line length 1 meter With boost components, the USB 5V input voltage through the components boost to 12V voltage 0.8 ~ 1A. Package included: 10 x 5V To 12V Power Line

10PCS Mini 0.5V 100mA DIY Polycrystalline Silicon Solar Panel

10Pcs Mini 1A Lithium Battery Charging Module Board With USB Interface Description: Charging method: linear charge 1% Charging current: 1A adjustable Charge accuracy: 1.5% Input voltage: 4.5V-5.5V Full charge voltage: 4.2V Charging indicator: Red charging green full charge Charging input interface: Mini USB Working temperature: -10C to +85C Reverse: NO Size: 25 x 19 x 10mm Note: Ampere meter can only be connected to 5V input end of the module. It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough. The connection wire should not be too long. Make sure the connect point is good. If the input voltage is too high, like 5.2V, the current will be less than 1000mA, it is normal. It is protection function, Auto-substract the charging current to avoid burn damage to chip. Input reverse has no effect on the chip, but the output (battery terminals) reverse will burn chips. Applications: This module is used for single-or multi-section parallel lithium lithium rechargeable battery, charging from the USB port to take power. Package included: 10 x 1A lithium battery charging module

FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA Description: This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, its very efficient (over 90% efficient when driving an 8Ω speaker at over half a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. There's even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain. This board is a welcome upgrade to basic "LM386" amps! CJMCU The A+ and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio- pin to ground. The output is "Bridge Tied" - that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly. CJMCU Comes with a fully assembled and tested breakout board. We also include header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can easily attach/detach your speaker. You will be ready to rock in 15 minutes! Features: - Output Power: 2.5W at 4Ω, 10% THD, 1.5W at 8Ω, 10% THD, with 5.5V Supply - 50dB PSRR at 1KHz - Filterless design, with ferrite bead + capacitors on output. - Fixed 24dB gain, onboard trim potentiometer for adjusting input volume. - Thermal and short-circuit/over-current protection - Low current draw: 4mA quiescent and 1uA in shutdown mode Note: Speaker is not included, use any 4 ohm or greater impedance speaker.
