The Osprangle is a slightly modified version of the Osprette V3, fit for a rectangular case. The case in question is from the Equals 60 from Boardsource. The keyboard is a 34-key unibody that runs on any pro-micro compatible daughterboard. It comes with bluetooth support by way of battery terminals and a power switch.
To order one of these from JLC, just upload the osprangle.zip archive to the Order Now page at https://jlcpcb.com,
and make sure to set a 1.6mm thickness. Removing the order number is always recommended.
More to come when PCB's arrive!
