DC8V～40Vを入力し、12V/3A(最大)を出力する工業用グレードの昇降圧DC/DCコンバータです。大きなヒートシンクと保護機能を備え、入力が変化している間(バッテリーの充電/放電)でも安定して負荷(12VルーターやWi-Fi機器など)に電力を供給することができます。

Description。The SparkFun Multiplexer Breakout provides access to all pins and features of the 74HC4051， an 8-channel analog multiplexer/demultiplexer. The 74HC4051 allows you to turn four I/O pins into eight multifunctional， individually selectable signals， which can be used to do everything from driving eight LEDs to monitoring eight potentiometers.。The 74HC4051 can function as either a multiplexer or a demultiplexer， and it features eight channels of selectable inputs/outputs. The routing of common signal to independent I/O is set by digitally controlling three select lines， which can be set either high or low into one of eight binary combinations.。One half of the board breaks out the control signals(E， S0-S2)and common input/output(Z). The other side provides access to all eight independent I/O's(Y0-Y7). Both sides include supply and ground connections(VCC， VEE， GND).。Get Started with the 74HC4051 Breakout Guide。Features。Switches analog or digital signals。8 channels controlled by 3 select inputs。Wide voltage supply range：2 -- 10V。Bipolar supply support(e.g.， ±5V)。Optional enable input。Breadboard compatible breakout

Description。This is a 16mm deluxe thumb joystick and is very similar to the 'analog' joysticks found inside PlayStation controllers. Directional movements are provided simply by two potentiometers - one for each axis. These 10k potentiometers will read the position changes for the joystick's full range of physical motion. This joystick also has a select button that is actuated when the joystick is pressed down.。The mechanical parts found in this joystick are mostly metal and are considered far sturdier(rugged， if you will)than other， plastic joystick options.。Note：。This thumb joystick does not include a top cap and it will need to be purchased separately. Additionally， the leads on the housing of this joystick are much thicker than the leads on the trimpots & push button components. When soldering to BOB-9110， we recommend using a pair of fine tip tweezers to guide each pin into the correct hole before pushing down.

Description。This is a common 555 timer/oscillator from TI. A classic for all of those first year circuits projects where you need to blink an LED， generate tone， and thousands of other great beginning projects. Google around for a huge list of resourc

Description。The SparkFun Qwiic EEPROM Breakout is a simple and cost effective option to add some extra storage space to any project. With 512 kilo-bits(or 64 kilo-bytes)of storage， this product is great for any microcontroller that doesn't have any
