Product Description
The JX-887Y is a highly efficient, integrated DC-DC step-up booster and intelligent charging management module designed for building high-performance DIY power banks. Compatible with 3.7V Lithium-Ion (such as 18650 cells) and Lithium-Polymer (Li-Po) batteries connected in parallel, this compact board safely boosts low battery voltages up to a stable 5V DC output. It features dual USB Type-A output ports capable of delivering up to a combined 2A charging current to power smartphones, development boards, and remote IoT nodes. Outfitted with onboard status LEDs and comprehensive protection circuitry against overcharging, over-discharging, and short-circuits, it offers hardware developers and electronics enthusiasts a robust, safe, and space-saving solution for portable power regulation.
Pinout / Layout Connections
The module features clearly labeled surface pads and standard physical ports for straightforward integration:
-
Battery Input Solder Pads:
-
B+ Pad: Connects directly to the positive terminal of the 3.7V lithium battery bank.
-
B- Pad: Connects directly to the negative terminal of the 3.7V lithium battery bank.
-
-
Output / Input Interfaces:
-
Dual USB Type-A Ports (OUT 5V): Provide parallel 5V power distribution channels for dual-device charging up to 2A total.
-
Micro-USB Port (IN 5V): Serves as the dedicated charging input interface to safely replenish the connected battery bank from a standard 5V power adapter.
-
-
Capacity Indicators: Four onboard surface-mount LEDs that display the current battery charge level in 25% steps.
