Product SEN-10239 | about 2 years ago

reemrevnivek:

From the picture, it looks like it’s been dunked in epoxy. Is that true?

I’m wondering if I can cut and/or solder through that shiny crud that’s covering the PCB […].

From my experience, you can use an x-acto knife to scrape away the conformal coating in the same way you’d remove solder mask to get to the copper layer.

Is there a MFG part number, or a datasheet for these? That would certainly make it easier for us to make the correct footprint.

That is the protection circuit. Typically you either need to release the load (just unplug the battery) or charge the battery for a second to get it should let go.

buy a couple, drill some holes, let us know if they work? :D

i wrote a little sketch (arduino-0017) that fades the leds as you scroll up and down. see it at:

works much better with the blue and red leds though… the green one is kind of weaksauce.

The data sheet Fig. 42 shows what the enable circuitry looks like internally. I would agree that it looks like it is fine to tie the on/off to Vin and turn it on.

Product DEV-09147 | about 3 years ago

got mine today. works great. super cool to be able to do usb with 2 i/o and 3 resistors.

Product COM-09320 | about 3 years ago

Can we get part numbers or datasheets for the LEDS?

i think you can use the triac to drive lvdc stuff, however you’re better off with something different. if i had to pick from the sparkfun bin, you could use something like ROB-08903 or ROB-08905. or just a general switching component of your choice (mosfet, bjt, little relay, ect.)
