Seeed Studio nRF52840 and Wio-SX1262 Kit Keyfob Case

This is a very tight fitting case with very little tolerance. Minor trimming with a xacto knife might be necessary, especially around the “rim” on the back when snapping it into the front.

The 100mAh battery does not take all the space, so you could potentially go a little larger.

Note: The antenna placement is less than ideal, and I have not yet had an opportunity to do any range tests with the device.
