 +**TODO:**
 +  * Remove 2x Large Reservoir capacitors - not required
 +  * USB Vcc connected to USB Vin on KL25z board - will also charge from KL25z USB sockets.
 +  * Use larger SMA socket footprint - For UK-available parts
 +  * Add jumper to switch off KL25/Radio supply from lipo/​charger - allow switching off/​isolating lipo charging
 +    * 40mA Precharge Current for dead lipo was barely enough to power board, let alone charge the Lipo as well.
