Cargador micro USB para baterías de litio TP4056 5V 1A para proyectos Arduino

El mòdul TP4056 està dissenyat principalment per carregar bateries Li-Ion i Li-Po d'una sola cel·la (3.7V nominal, 4.2V de càrrega completa). No és apte per a altres tipus de bateries ni per a configuracions multicel·la en sèrie. La capacitat ideal de la bateria hauria de ser com a mínim igual al corrent de càrrega (1A), però es recomana ajustar aquest valor segons les especificacions del fabricant per maximitzar la vida útil. Per a cel·les de menor capacitat, el corrent de càrrega pot ser excessiu.

El TP4056 no disposa de protecció contra polaritat inversa. Si es connecta la bateria al revés, hi ha un alt risc de danyar tant la bateria com el mòdul i podria provocar curtcircuits perillosos. Es recomana extremar la precaució en connectar i verificar sempre la polaritat abans d'alimentar el circuit.

Es pot alimentar mitjançant el connector micro USB estàndard (5V), o bé a través dels pins d'entrada 'IN+' i 'IN-' soldant cables directament a la placa. El voltatge d'entrada s'ha de mantenir entre 4.5V i 5.5V per a un funcionament correcte. Superar aquest rang pot danyar el mòdul.

El mòdul està dissenyat per operar entre -10°C i +85°C. En càrregues properes a 1A, el xip i la PCB es poden escalfar notablement; si la ventilació és insuficient, reduïu el corrent o assegureu una dissipació tèrmica addicional. Es recomana no superar els 60°C a la pròpia placa, i monitoritzar sempre la temperatura en entorns calorosos per evitar degradació prematura o fallades.

The TP4056 module is mainly designed for charging single-cell Li-Ion and Li-Po batteries (3.7V nominal, 4.2V full charge). It is not suitable for other battery types or for multi-cell series configurations. The ideal battery capacity should be at least equal to the charging current (1A), but it is recommended to adjust this value according to the manufacturer’s specifications to maximise service life. For lower-capacity cells, the charging current may be excessive.

The TP4056 does not have reverse-polarity protection. If the battery is connected the wrong way round, there is a high risk of damaging both the battery and the module, and it could cause dangerous short circuits. Great care should be taken when connecting it, and polarity should always be checked before powering the circuit.

It can be powered via the standard micro USB connector (5V), or through the 'IN+' and 'IN-' input pins by soldering wires directly to the board. The input voltage must be kept between 4.5V and 5.5V for correct operation. Exceeding this range may damage the module.

The module is designed to operate between -10°C and +85°C. At loads close to 1A, the chip and PCB can become noticeably warm; if ventilation is insufficient, reduce the current or provide additional heat dissipation. It is recommended not to exceed 60°C on the board itself, and to monitor temperature in hot environments to avoid premature degradation or failure.
