+  * Seeed Studio Xiao nRF52840
+    * Be extra careful with soldering battery leads!
+    * Careful with brown-outs when voltage gets too low!
+  * CN3791 MPPT charging board
+    * Xiao's charging circuit sucks and will cause brown-outs when powering through USB!
+    * TP4056 also sucks.

+  * 18650 battery
+    * Or any other 3,7 V lithium battery.
