硬币 - 电池到USB适配器板将过时的足迹变成电力输入

Alpenglow行业的Carrie Sundra设计了一个巧妙的适配器板，该板将硬币电池的足迹转换为USB电源输入，旨在遵守新的电池安全法规，需要通过螺丝保留电池。

Alpenglow Industry's Carrie Sundra has designed a clever adapter board that turns coin-cell battery footprints into USB power inputs — designed to work around new battery safety regulations which require batteries be retained by a screw.

"Hey soldering kit makers," Sundra writes by way of introduction to the board. "Struggling with new coin cell regulations and have a pile of PCBs with coin cell battery holder patterns on them? I made a thing for ours that converts them to USB power, maybe it's handy for you. Ship this instead of a CR2032 holder and boom, your kit no longer contains or uses a coin cell, no compliance needed. It's designed for side-slide style holders (SMT or through-hole) and easy to solder."

“嘿，焊接套件制造商，” Sundra通过介绍董事会写道。在苦苦挣扎的新硬币细胞法规上，并在上面有一堆带有硬币电池电池持有人图案的PCB？我为我们的东西做了一件可以将它们转换为USB功率的东西，也许对您来说很方便。将其代替CR2032持有器和吊杆，而不是cr2032持有者和吊杆，您的套件不再包含或使用coin coin，不需要一个符合型的solarsians。

The idea for the board came about following the introduction of or more rigid enforcement of battery safety laws around the world. Where it was previous acceptable to have a friction-fit battery holder for coin cells, it's now required that the cells be retained by a screw — to prevent a curious child pulling the battery out and swallowing it.

董事会的想法是在世界范围内引入或更严格地执行电池安全法时的想法。如果以前可以接受硬币电池的摩擦电池持有人，现在要求通过螺钉保留电池 - 以防止一个好奇的孩子将电池拉出并吞咽。

The board is designed to be soldered onto the footprint of a push-fit coin-cell holder, with no changes to the underlying PCB design required. A 10Ω resistor on the output mimics the resistance of a typical coin cell while on-board hardware limits current to 250mA and provides other protections.

该板的设计旨在将其焊接到推式硬币电池支架的足迹上，而所需的基础PCB设计没有更改。输出上的10Ω电阻模仿典型的硬币电池的电阻，而车载硬件将电流限制为250mA，并提供其他保护措施。

"If this is useful for you, let me know," Sundra writes. "I'm about to get a pile of them made and can do bulk pricing if you want 100 or more. Still need to finalize cost, but can prob do somewhere in the 35-75 cent range depending on qty. I'm also getting some 5V output ones made for our kits that use 2× 2016s stacked in a holder. This passes USB out with a 10-ohm inline resistor and PTC fuse with a 250mA current limit."

“如果这对您有用，请告诉我。” Sundra写道。 “如果您想要100或更多，我将要制作一堆批量定价。仍然需要确定成本，但根据数量的不同，可能会在35-75美分的某个地方进行。我还可以在使用2×2016的套件中获得一些5V输出的产品，该套件堆叠在持有架中的2×2016，这将与10-ohmmmmmmmmmmmmmmm inline Comply andline Comply和Ptccm concm forcy and linline limim anfcm fuse and a fline。
