RFM69 BMP280 Remote
Description
This is a case for an RFM69CW BMP280 remote. It's part of a larger project. For more details see <a href="https://www.instructables.com/id/Hiking-Data-Logger-Using-RFM69CW/" name="instructable">Hiking Data Logger</a> on instructables.com. - BMP280 Base.stl - 20% fill, High resolution, no support - BMP280 Cover.stl - 20% fill, High resolution, no support - BMP280 Base+DC.stl - 20% fill, High resolution, no support BMP280 Base+DC adds a hole for placing a power jack for charging the battery. See www.aliexpress.com/item/32919971020.html for the plug, connector and rubber seal. I wrapped a very common lipo charger using: BMP Charger Base.stl BMP Charger Cover.stl The lipo charger is www.aliexpress.com/item/4000522397541.html For the small lipo battery you need to replace the resistor R3 with a 3.3K to reduce the charge current. This will also allow you to plug it into any USB port without the port complaining about it drawing too much current. I used 2mm acrylic rod as wave guides for the LEDs on the charger. The rods are cut, polished and epoxied into the two holes on the charger cover.
