Li-po Rider

Hi everyone, With this Lipo Rider, is it possible to limit the current of the USB output at, for example, 150 mA ? I can see on the top view of the PCB: R7 R8 R9 R10, near the usb connector. Are this placements waiting for resistors, and if yes, can you explain me, please, the way to limit the current ? Thank a lot for answering. Best regards Phil

Hi Philippe.Those resistors are reserved for some special devices,such as iphone.And the current of output is depended on your load.If your load is too small,the current would be more larger,so maybe you can add a external circuit to your devices,but none of business of those resistors.

Are there pads for attaching wires to the status LED traces, so you can easily wire them to Arduino pins to monitor battery charging status?

Hi Chris, you could refer to its schematic, find DONE pin of CN3065, solder a wire to connect it to your Arduino pin to monitor charging status. Another method, find LIPO_BAT pin, monitor the voltage by Arduino analog port.

Hello, I would like to ask if there is USB data on the Li-Po Rider. I would like to program and use my Teensy when the USB is plugged into the Li-po, and let it ride on battery power when it's not. I would like to know if it is possible to just use one connection to charge and transfer data (charge via Li-po Rider and transfer data with Teensy).

Hi,you can't program it.This product is just a charger.

I want to make two modifications in my 1.0 board: 1. I want to drill at least one hole in the board for standoffs, but I'm afraid of making shorts. Are both the top layer and bottom layer copper fill connected to GND? or is one of them connected to VDD5? Anyone, one of the drills will probably be through the Seeed logo, where there is only one layer :-) 2. I need a higher output current at 5V or above (driving a DC motor), so I want to solder an LM2577 based module to BATT_IN (on C8). Is there any problem with that? The module requires a minimum 3.5V input. Will a typical LiPo voltage fall that low before being close to being drained? I have your 6000mAh LiPo 3-cell pack, rated at 2000mA max output current. thanks, Udi

Hello,sorry for the late reply . Both the top layer and bottom layer copper fill connected to GND. We are sorry we didn't test like this before , thanks for you understanding.
