TP4056 5V Micro USB 1A 18650 Lithium Battery Charging Board Charger Module

• Dual Function: 1) Charge lithium cells from a 5V power source 2) Protect battery from over-discharge and over-current
• Charge input: 5V DC • Maximum charge current: 1000mA • Charge cut-off: 4.2V
• Discharge protection cut-off: 2.5V • Over-current protection cut-off: 3A
• Micro-USB input • Size: 2.6x1.7cm

This is an enhanced USB-powered module for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method.

This module provides constant-current/constant-voltage (CC/CV) charging, along with protection against over-voltage, over-discharge, over-current and short circuits to protect the battery and the device that it is powering.

The device to be powered by the battery is connected to the module's OUT+ and OUT- connectors and the battery is connected to the B+ and B- connections. When connected to USB power, the module provides up to 1A charge current until the battery is charged, then switches to a constant voltage mode to keep it charged.

During use, if the battery voltage drops below about 2.4V, the DW01A protection IC disconnects the battery from the OUT connectors, disabling discharge to protect the battery from running at too low and self-destructing.

When the module is then connected to USB power, it will trickle charge the battery to 2.9V (the over-discharge release voltage), at which point the charge current will be linearly increased to 1A maximum and the module will reconnect the battery to the OUT connections, allowing discharge of power from the battery to a connected load. Although the module cuts output power from the battery during an over-discharge situation, it still allows trickle charging of the battery to occur.

The module also protects against overcurrent and short-circuit protection - it will cut the output from the battery if the discharge rate exceeds 3A or if a short-circuit condition occurs.

This module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as 16550s and 18650s that don't have their own protection circuit. It can charge two cells in parallel, however since the two cells share the charging current, they take twice as long to charge as a single cell.

Display to be connected to arduino, atmel328p, raspberri pi etc... as a visual output display. OLED is already mounted to breakout style circuit board for easy application.

In arduio IDE the selected programmer should be "AVRISP mkll". If programming a stand-alone 328P the selected board should be arduino/genuino uno

The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V/3V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.

The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.

This board has TX and RX LEDs that make it a bit better to use over the FTDI cable. You can actually see serial traffic on the LEDs to verify if the board is working.

This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). Our Arduino Pro boards and LilyPads use this type of connector.
