Hello, and welcome to the today's blog contribution.
One Temperature sensor in the greenhouse, one Movement dispatch rider in the garden gate, or one Radio push button switch for Smarthome lamps - everybody far away of an outlet.
Who would like to move no power supply line in such a situation and bore holes, is able on the application fromLi bottom or Li ion accumulators fall back. However, these need one Loading regulator how ours TP4056, as well as one Boost converter how thisTap dance MT3608 DC-DC up module.
From now on we offer to you in our shop a compact alternative: this Power bank TP5400 USB module.
The TP5400 combines one Lithium battery loader with one Step-Up tension converter, he the Ausgansspannung on 5 V regulates.
The advantages are obvious:
Very much compactly
Boost tension converter on 5 V
+ Unloading protection
+ Short circuit protection at the exit
Recognition from Loading circuits from To mobile phones
+ Very much low one Own unloading if no consumer is connected (0.1 mA)
Loading regulator switches off with 4.2 V
On the board 2 LEDs are obstructed:
The red LED shines during the loading process. As soon as the accumulator is loaded, shines a green LED.
According to data sheet the charging current amounts to 5 V 1000 mA, and at the exit puts the module for a short time up to 1200 mA with 5 V ready. Nevertheless, with these values care is offered - 1200 mA lead without fail to the Überhitzung of the chip.
With 3.7 V of Li bottom accumulator in 3800 mow the module in the test delivers stable 800 mA.
If in the running company a stream spring is connected, the accumulator is loaded, and the consumer is supplied at the same time about USB with stream.
In our test construction I pursue our I2C scanner which pulls permanently 40 mA for over 48H with a Li bottom accumulator. The accumulator still has just 50% - would hold out another just 2 days. A good result for such a compact accumulator.
We find the new power bank TP5400 USB module very practical, and each he would like to use his projects at remote places or also on the way, a handful of these modules should always have in his assortment box.
I hope the today's contribution was informative and has made you curiously on the new product. We are tensely what you with the module plan, and please us to get to know what you have moved with the TP5400.
In the tomorrow's contribution we show you how you can use the module as reasonable USV for microcontrollers.
A lot of fun experiment with, and up to the next spot.
