Charger module with TP4056 controller Click for larger picture This charger is a very small module for DIY people, it uses the TP4056 controller and standard configuration is with 1A charge current. It does not include any power supply or tray. It did not include any documentation either, just a couple of boards. The review is about a specific charger module, but any module with the TP4056 will have identical performance.
I got it in an envelope with 5 circuits on 2 boards and nothing else. The boards is precut and very easy to break apart. A close study showed that there was a small difference between the size of the boards. The board needs a 5 volt power supply, this can either be from a mini usb connector or soldered directly to the board. The charge led will be on when charging and it will be flashing when no battery is connected. The backside of the board has some internal connections and the connections points are also accessible here. The board is small, the battery is a AAA battery. TP4056 LiPo Battery Charger For RC Toys. Lithium Polymer (LiPo) battery is a type of rechargeable battery that provides high energy storage to weight ratios in an eternal variety of shapes and sizes. LiPo batteries has taken the electric RC gizmos world by storm,especially for Radio-Controlled (RC) toys like electric helicopters, airplanes and boats.
Unlike conventional NiCad (or NiMH) cells that have a voltage of 1.2 volts per cell, LiPo battery cells are rated at 3.7 volts per cell. The benefit here is fewer cells can be used to make up a rich battery bank. In practice, RC LiPo battery packs should have at least two or more LiPo cells hooked up in series to provide higher voltages. For larger RC models this number may be as high as 6 cells! 3.7 Volt LiPo battery /1 cell x 3.7 volts (1S) Charging LiPo cells/batteries is not an easy task. Fortunately, single-chip solutions are now widely available for Li-Po battery charging.
Furthermore, the TP4056 can work within USB and wall adapter. Lab Note: Calcul Résistance. Comment se servir du tableau ? Pour obtenir la valeur de la résistance souhaitée il suffit de remplir cases par vos propres valeurs et les cases résistances et puissances se rempliront toutes seules ! Si vous avez des valeurs avec des virgules, remplacez les par des points ( . ) exemple si vous voulez rentrer 3,6V rentrez 3.6V. Tension aux bornes du montage Cette tension est la tension qui alimente tout votre montage c'est-à-dire une pile, un générateur, une alimentation de PC etc ...
Cette valeur n'a rien à voir avec les valeurs que vous allez éventuellement trouver sur le site ! Tension de fonctionnement de la led Cette valeur se trouve dans le site : quand vous regardez un produit vous n'avez qu'à cliquer sur détail produit pour obtenir toutes les informations nécessaires au calcul de la résistance idéale Intensité de fonctionnement de la LED Résistance réelle Cette valeur vous donne donc la valeur de la résistance idéale à votre montage.

Dear Customers, We are sorry to inform you that the PCB prototype service is temporary suspended due to the lack of free capacity. As you know we had long vacation in August and people was keep sending PCB prototypes even while we were on vacation, this created so huge backlog that we couldn't repond to all PCB jobs for more than a week after we resumed work.
On top of this our lines usually are loaded close to 100% with the production of our own development boards and having such additional big load start to mess with our production schedules and delay our development boards production and shipments which is unacceptable. We are sorry for this situation and we expect this to improve in the next months, so we can re-enable this service at fist possibility, but effectively from September 17th the PCB prototype service is suspended. We do offer people to put many boards on same panel, and we did offer panelization service free of charge. 1. 2. Why?
