A small, but mighty power supply. This board was designed to be as small and inconspicuous as possible. Pop in a AAA battery, flip the power switch, and you will have a 5V supply to power your LilyPad circuit. Good up to 200mA. Short circuit protected.
This board has AAA battery clips but can use an input from 1.2V to 5V. Our lithium polymer batteries are a good, rechargeable alternative.
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable - but be sure to remove the battery!
Note:A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

1 sets Handy Portable Resistor Kit for Starter Kit UNO R3 LED potentiometer tact switch pin header

Model: Ternary lithium battery 3 series 4 series 5 collusion protection board
This protection board uses mature protection circuit, special IC, imported large current ultra-low internal resistance MOS (single MOS internal resistance is as low as 3 milliohms), with perfect and stable charging and discharging of various protection functions.
Small size and large current can be used for power tools, model aircraft and other occasions with large current.
This protection board is a power type high current lithium battery protection board, suitable for large current equipment, such as power tools, motors, electric drills and other equipment.
Notes:
Note 1: B- and C- wires should be connected with thick wire, and ensure that the welding pad is correctly welded with the positive and negative terminals of the corresponding equipment.
Caution 2: Before installing the protection board, ensure that the batteries are well matched (the voltage difference of each battery is no more than 0.05V, the internal resistance difference is no more than 5m ω, and the capacity difference is less than 30mAh). The protection board is used to protect each battery string. If the voltage of one battery string is too high or too low, it will be protected. The better the consistency of the battery, the longer the power of the battery, the better the performance of the protection board.
Note 3: Connect a single battery to a required number of battery strings, and then connect the battery strings in series.
Note 4: When three batteries are connected in series, ensure that the voltage of each battery is the same. If the voltage of each battery is different, charge each battery separately and use it in series. In the discharge test, the group of batteries whose voltage drops quickly is the poor battery.
 
Note 5: do not mix the good battery and poor battery use together, the capacity of the battery pack, internal resistance as close as possible.
Note 6: This guard plate cannot be used for lithium iron phosphate batteries.
 
Note 7: Do not use the lithium battery protection plate in series.
FAQ:
1. Can MY battery use this protective board?
A: There are two issues to consider whether you can use this protection board: how many strings of your battery, you should buy the corresponding number of strings of protection board. Second, what is your battery made of? We have lithium iron phosphate and polymer two parameters of the protective plate, if your battery is lithium iron phosphate single nominal 3.2V need to choose lithium iron phosphate 3.2V in the classification, if polymer (ternary, cobalt acid, lithium manganese oxide battery) single battery nominal 3.6V (or 3.7V) please choose polymer 3.7V classification.
2. How can I tell what my battery is made of?
Answer: you can take a look at your battery nominal voltage, lithium iron phosphate battery is generally standard 3.2V, other batteries are generally standard 3.6V or 3.7V, you can also directly ask the seller of the battery is what material of the battery, many buyers said my battery is 18650 or 26650 soft package, this is the appearance, not the material oh! We cannot determine your battery protection parameters according to this.
3. How many protective boards should I choose?
A: How many amps to choose depends on your load power, our protection board is the same port output, output 1 series of current is 16A, 2 series of current is 25A.
4. My battery is 20AH, can I use this protection board?
Answer: your battery capacity size and use the current size of this board actually have no direct relationship, the capacity is not the battery is large, mainly look at the continuous current, that is to say your load is bigger, you choose the protection board continuous current is bigger, with the battery capacity has no direct relationship.
5. How to set the charger voltage?
 
Answer: lithium battery must be charged with a special charger for lithium battery, do not use lead-acid battery charger, lead-acid charging may have high voltage breakdown of the protection plate MOS tube, resulting in protection plate overcharge is not protected. Charger voltage setting: use your battery string number *4.2V which is the charging voltage of non-iron lithium battery, the charging voltage of iron lithium battery string number *3.60V which is the charging voltage of iron lithium battery, the charging current standard is 0.2 times of the capacity.

Features:
 
◦This product is a booster coil production suite, the circuit is simple and reliable, with a professional line drawings, electronic research convenience enthusiasts
 
◦Uses: high school science experiment, electronic equipment, negative ion generator, scientific small production. This circuit is generated when the stable high frequency arc, high temperature, can easily ignite combustible materials, so it was called the plasma lighters
 
 
Parameter:
 
◦15KV transformer outside dimensions of approximately: 27×16×21mm
◦Input voltage: DC 3.7V-4.2V (limit 12v, easy to damage not recommended, this transformer is equally applicable to 12V input voltage, but requires a corresponding increase in the base of the feedback resistor to about 150Ω ~ 1.5KΩ, its resistance should be large to replace a small adjustment, or burned transistor or transformer)
◦Input Current: <2A
◦Output voltage: approximately 15KV (please pay attention to safety when used)
◦Output Current: ≤0.4A
◦High voltage bipolar ignition distance: ≤0.5 cm
 
◦When the product input termination 3.7V-4.2V power supply, the secondary high voltage output is not connected to high-voltage rectifier diodes and capacitors, output terminals levels ≤1.5cm long can produce purple high temperature arc, no crackling, but the temperature is very high , you can easily and instantly point cigarette paper, or even very thin wire burned Sparks (such as junior high school chemistry experiment thin wire in oxygen combustion scene, but not as good as oxygen so intense.)
 
 
Transformer structure:
 
There are two primary windings, a primary winding, a feedback winding, the secondary output of high pressure. Other: 15KV transformer designed for maximum output, limit output can not exceed 15KV, is one centimeter arc, a higher output voltage is likely to damage the transformer.
 
 
PCB board size: 4.2CM * 3.2CM * 0.16CM;
Installation Notes:
 
1). With the PCB board parts better production, in which the transformer line of thick line and thin line, this should pay attention to the other components by the board of silk symbols and parameters of welding on the line. Transformer board has done three pads, in which the middle of the pad hole is relatively large, the hole at the same time welding a thick enameled wire and a thin enameled wire, thick enameled wire and fine enameled wire do not use the same side, such as with the left Thick lines and the right side of the thin wire into or with the left side of the thin line and the right side of the thick line welding into, in short, do not use the same side of the thick lines and thin lines can be.
 
 
 
2). In order to prevent the output 2-wire distance too far, resulting in no-load, you can weld a 3P pin at the output.
 
 
3). After the success of the production, if the output access to a high-voltage capacitor and three high-voltage rectifier composed of voltage doubler circuit, you can produce DC high voltage, you can make anion generator, wiring diagram is as follows:
