1. SparkFun LED 3W Aluminum PCB (Warmweiss)
5 very powerful 3W LEDs with over 200 lumens - warm white
Wherever a lot of light is needed, these powerful 3W LEDs are just right. The aluminium housing dissipates the heat ideally.
Important: Do not look directly into the LEDs - they really are very powerful.
Features:
- Forward Voltage: 3.4-3.6V
- Forward Current: 700mA
- Viewing angle: 140-150 degrees
- Luminous Intensity: 200-220 Lumen.
2. SparkFun Arduino Pro Micro 5V/16Mhz
The SparkFun Pro Micro Board is similar to the SparkFun Pro Mini, except that it features an ATmega32U4 onboard. The integrated USB transceiver allows the Pro Micro to be used as a keyboard, for example (like the Arduino Leonardo). This small board also includes all the other features we expect from Arduino: 4 ADC channels, 5 PWM pins, 12 digital I/Os, and a hardware serial connection. The board is powered by 5V and is clocked at 16MHz – just like the original Arduino. We offer only the latest revision without printing errors and with additional PTC fuses and protection diodes.
3. SparkFun Power Driver Shield Kit
This shield allows you to switch large loads on the Arduino using an ATX power supply or another power source. The RFP30N06LE MOSFETs make it easy to switch significant loads.
The board features 6 PWM outputs via terminal adapters. For the power limits, please refer to the datasheet for the MOSFETs.
In this revision of the shield, a protection diode has been added.
Included in the package are all necessary components as well as two pairs of stackable headers. However, if you want to stack another shield on top of the Power Driver Shield, you will need two layers of headers, as the MOSFETs are relatively tall.
4. SparkFun FemtoBuck LED Driver
This is the FemtoBuck, a small-size single-output constant current LED
driver.
Each FemtoBuck has the capability to dim a single high-power channel
of LEDs from 0-350mA at up to 36V while the dimming control can be
either accessed via PWM or analog signal from 0-2.5V.
For the FemtoBuck, we've increased the voltage ratings on the parts to
allow the input voltage to cover the full 36V range of the AL8805
driver. Since the FemtoBuck is a constant current driver, the current
drawn from the supply will drop as supply voltage rises. In general,
efficiency of the FemtoBuck is around 95%, depending on the input
voltage. On board each FemtoBuck you will find two inputs for both
power input and dimming control pins and an area to install a 3.5mm
screw terminal. Finally at either side of the board you will find
small indents or "ears" which will allow you to use a zip tie to
secure the wires to the board after soldering them down.
5. SparkFun Buck Regulator Breakout - 3.3V (AP3429A)
The SparkFun 3.3V Buck Regulator Breakout features the AP3429A from Diodes Inc, a 2A step-down DC-DC converter with an input voltage range of 2.7V to 5.5V. This full-size, 1in x 1in version of our buck regulator boards is configured to provide a regulated 3.3V output (from a 3.9V to 5.5V input voltage range), which is controlled by an enable (EN) pin. To dissipate excess heat, a 0.6in x 0.5in copper pad is provided to attach a heat sink to the bottom of the board. As a full-size buck regulator breakout, additional options for connecting input and output power are available. There is a pre-assembled screw terminal for a non-permanent connection, the option to solder on a barrel jack for an external power supply, and five PTH pins to create a more permanent installation. Our full-size buck regulators also come with a red power indication LED that lights up when the power output is enabled. This board has four mounting holes compatible with 4-40 hardware.
Features:
- Buck board:
- 1in x 1in PCB layout
- Three power input/output options:
- Pre-assembled 4-pin screw terminal
