Description:
 
 
The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board.
The USB transceiver inside the 32U4 allows us to add
USB connectivity on-board and do away with bulky external USB interface.
 
This tiny little board does all work for Arduino tricks that you're familiar with:
4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as
hardware serial connections Rx and Tx. Running at 16MHz and 5V,
this board will remind you a lot of your other favorite for Arduino-compatible boards but this little guy can go just about anywhere.
There is a voltage regulator on board so it can accept voltage up to 6V(Blue board)/18V(Black board).
If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC.
 
This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled.
We've also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit.
 
 
 
Features:
 
 
ATMega 32U4 running at 5V/16MHz
Supported under for Arduino IDE v1.0.1
On-Board MINI USB connector for programming
4 x 10-bit ADC pins
12 x Digital I/Os (5 are PWM capable)
Rx and Tx Hardware Serial Connections
Our Smallest for Arduino-Compatible Board Yet!

This is a super mini Solar Lipo charger based on the CN3065 - a single lithium battery charge management chip.
This Solar charger provide you with the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargable LiPo battery. Set-up is easy as well, just plug your solar panel into one side of the Solar charger and your battery into the other and you are good to start charging!
The output of the Solar Charger is intended to charge a single polymer lithium ion cell. The load should be connected in parallel with the battery. By default, the Solar charge comes set to a maximum charge current of 500mA with a maximum recommended input of 6V (minimum 4.4V). It’s recommended that batteries not be charged at greater than their capacity rating.
Features:
Solar panel input: 4.4-6V
Max charge current: 500mA
Interface: 2-pin JST connectors(or PH2.0)
Short circuit protection
Continuous Charge Current Up to 500mA
Battery status indication ( Red : Charging , Green: Charged )
Support USB Charge (Micro-USB Connector)
Size:2cm x 4cm

Programming software: AVR_fighter, PROGISP1.66, PROGISP1.67, PROGISP1.68 Compile lower or higher software, and burn it all at once, very convenient.
 
 
 
 
 

LM2596 LM2596S DC-DC 4.5-40V adjustable step-down power Supply module 
 
Name : LM2596 DC-DC Buck module
Input voltage :4V ~ 35V
The output voltage : 1.23V ~ 30V
Output Current :3A( Max)
Conversion efficiency:92% ( MAX )
Output ripple: <30mV
Switching frequency: 150KHz
Working temperature: -forty Five~ 85
Size :43mm * 21mm * 14mm(Long*Width*Hight)
Features:
1. the range of input voltage: 3.2 V to 40 V dc (input voltage must be higher than to the output voltage of 1.5 V above. Can't booster)
2. the range of output voltage: 1.25 V dc to 35 V voltage adjustable, high efficiency (92% ) largest maximum output current is 3A.
 
Instructions:
1. Power (3-40V), power indicator light, the module is working properly.
 
2. Adjust the blue potentiometer knob (clockwise rotation generally boost,counter-clockwise rotationTurn down) and reach with a multimeter to monitor the output voltage required voltage.
 
Note:
 
  Current work long hours is recommended for use in less than 2.5A, while adding bulkHeat sink (10W output above),because it is the step-down module, in order to ensure stable output Set,please keep the minimum 1.5V differential.
